Inleiding
Deze pagina gaat voornamelijk over het oplossen van problemen met Akonadi. Storingen zijn onvermijdelijk in de vroege stadia van de migratie. Veel mensen zijn de eerste tekenen vanAkonadi in KDE 4.4 SC en het zal velen verwarren. Voor een korte beschrijving van het doel van Akonadi, zie de Woordenlijst. Daar staan ook nuttige verwijzingen naar meer informatie. Zodra de onvermijdelijke aanloopproblemen voorbij zijn, is Akonadi een power-house dat bruikbaar is voor vele toepassingen.
De structuur begrijpen
U kunt natuurlijk ook gewoonKontact gebruiken om al uw adresboeken te beheren, maar als u een bijvoorbeeld back-upsysteem hebt, wilt u weten waar uw gegevens zijn en daarmee wordt omgegaan. Dat staat beschreven op de pagina Akonadi en AddressBook
Tips voor het oplossen van problemen
- Voeg bij het melden van problemen met de Akonadiserver altijd het uitgebreide zelftestrapport toe.
U kunt dit rapport aanmaken dor het dialoogvenster zelftest dat automatisch wordt weergegeven als de Akonadiserver niet kon opstarten. De zelftest staat in de kcmmodule, die toegankelijk is via:
kcmshell4 kcm_akonadi
- Het handmatig starten van de Akonadiserver vanaf de commandoregels kan ook bruikbare informatie opleveren. Start de server door in een console het volgende commando uit te voeren:
akonadictl start
Met deze opdracht kan de Akonadiserver weer gestopt worden:
akonadictl stop
Dit commando geeft meer nuttige informatie:
akonadictl status
Veelvoorkomende problemen
Kontact start niet en geeft geen informatie
Als Kontact niet start, en u ziet geen foutmeldingen, controleer dan of Akonadi draait. Akonadi moeten starten als daarom wordt gevraagd. Als dat op uw systeem niet werkt, start het dan voordat Kontact opstart als u gemigreerde bronnen hebt; waarschijnlijk is dat KAddressBook. Gebruik het icoon voor Akonadi in het systeemvak, dit wordt actief na het uitvoeren van "akonadi" inKRunner, of typ de opdrachten in konsole om het te starten.
Kontact start niet, versie II
Kontact has been known to be hit after an update. If this happens, try starting KMail, KOrganizer or any of the other applications from KRunner (or Konsole). Chances are high that they will work as stand-alone apps while you find what went wrong. This mainly affects version 4.4.0.
Map niet gevonden: "/Local"
Sommige gebruikers hebben deze foutmelding gemeld als Kontact niet wilde starten. In een aantal vroege versies van 4.4 lijkt een bug te zitten in de migratie die KMail aangeeft om te kijken ~/.local/share/Local, een map die niet was aangemaakt. De oplossing hiervoor is om niet te proberen dit probleem te verhelpen, maar terwijl KMail en/of Kontact afgesloten zijn, de Akonadi Console te openen:
- Gebruik KRunner, Alt-F2, of
- "akonadiconsole" konsole
Verwijder vervolgens de bron die aangeeft voor lokale e-mail te zijn. Nu hoort Kontact of KMail te starten, en wordt de nieuwe bron aangemaakt met een verwijzing naar ~/.local/share/local-mail.
Ja. Als uw adresboek correct is gemigreerd, wordt een nieuwe bron aangemaakt als ~/.local/share/contacts/.
Wat zijn /usr/bin/akonadi_maildir_resource en /usr/bin/akonadi_maildispatcher_agent?
The akonadi_maildir_resource is created automatically by the akonadi_maildispatcher_agent, while the latter is always started together with the Akonadi server as it provides basic functionality (e.g. sending mail) that is used by all mail applications that are (and will be) based on Akonadi. So it is ok that these two are running, as a user you can simply ignore them. This autogenerated akonadi_maildir_resource will always point to ~/.local/share/local-mail/ which is your "Local folders" account where your local folders and emails will be stored.
E-mail wordt op dit moment in KDE SC 4.4 nog niet gemigreerd.
Nepomuk Indexing Agents zijn uitgeschakeld
Kontact werkt nu, maar u blijft de volgende melding zien:
The most common reason for this notice is that Nepomuk is simply disabled in System Settings. Please try enabling it in System Settings under by checking "Nepomuk Semantik Desktop" and clicking "Apply".
If this does not help (or if the option was already checked when you got the error) and if you have previously been using prereleases of KDE SC 4.4, you may be affected by a change to the database layout (due to an upgrade of the Virtuoso database server from version 5 to version 6; production releases of KDE SC 4.4 are expected to be shipped with Virtuoso version 6). The following commands should get it working again:
qdbus org.kde.NepomukServer /nepomukserver org.kde.NepomukServer.quit rm -r ~/.kde/share/apps/nepomuk rm -r ~/.kde4/share/apps/nepomuk nepomukserver
Note that the above commands will not enable Nepomuk permanently if it isn't already enabled, you have to use System Settings for that.
A running Nepomuk is necessary to have a working Akonadi, and thus a working Kontact. However, you can disable the Strigi file indexer, which is not needed for Kontact. Strigi file indexing is used for desktop searching only, which is unrelated to Kontact. Just make sure Nepomuk itself is running correctly for Kontact.
In Kontact, Nepomuk is used for many different things, ranging from displaying upcoming birthdays, over handling free/busy lists to showing a contact photo in the message viewer. If Nepomuk is not running, several different things in Kontact will cease to work. The notice is there to warn you about the reduced functionality. Enabling Nepomuk as described above fixes the problem.
U kunt controleren of Nepomuk correct draait met dit commando:
akonadictl status
Ik wil mijn huidige adresboek en agenda gebruiken. Kan dat?
Yes. When you use the Akonadi Console to add a resource it allows you to choose as Standard Addressbook - point that to your std.vcf should work fine. Migration does not destroy your old addressbook. You can continue to use it, though you will lose any benefits that Akonadi can bring. Alternatively you can have both an Akonadi addressbook and your original one, for a time, if you feel safer that way.
Ik zie geen gegevens in mijn adresboek
At the moment, the cause of this is not identified, but the cure is simple. Close Kontact, and start KAddressBook as a stand-alone application. After you close it you will be able to use it within Kontact. It seems that something is not being triggered when Kontact launches, and I expect this to be identified and fixed soon. This seems to mainly affect version 4.4.0.
Mijn contacten worden niet weergegeven als ik op Selecteren klik in KMail
Check . Make sure that your Akonadi controlled address book(s) are listed there - add them if necessary. At the same time, it's a good idea to make your main Akonadi addressbook, usually called "Personal Contacts", is set to be the default. More details of how this can be found in here.
Hoe krijg ik mijn groupwareadresboek terug?
Twee oplossingen: met het oude framework of met het nieuwe.
Old framework: In akonadiconsole, add a "KDE Address Book (traditional)". The KDE Address Book means you can set up old kresources for Akonadi. In the configuration of "KDE Address Book (traditional)", you point it to an "IMAP over KMail" KResource and in KMail, the groupware options should be enabled. This should work for Kolab, eGroupware and similar addressbooks - you will need to check the options to make sure that the correct type is selected.
New framework (only tested with Kolab): In the Akonadi configuration module add an "IMAP E-Mail Server" resource, and set up your mail server name, username and password, then click Auto-Detect. Run this command to see it:
kcmshell4 kcm_akonadi
Then add a Kolab resource. The next step is to wait for the imap resource to synchronize, which can take quite a long time. The status will appear in the Akonadi configuration module. If nothing happens, try restarting akonadiserver. After some time the Kolab addressbook(s) should appear in KAddressBook.
Er zijn lange vertragingen bij het verzenden van e-mail
Dit gaat gepaard met het bevriezen van KMail totdat de e-mail daadwerkelijk is verzonden.
A bug has been found in the way Nepomuk checks addresses, which can cause huge delays. This is fixed for SC 4.4.1. If you cannot get 4.4.1 yet, there is this work-around:
Close Kontact, or KMail and KAddressbook if you are running stand-alone apps. Disable Strigi in SystemSettings. Stop Nepomuk, delete the database and restart nepomukserver. The actual commands you need are (as user):
qdbus org.kde.NepomukServer /nepomukserver org.kde.NepomukServer.quit rm -r ~/.kde/share/apps/nepomuk rm -r ~/.kde4/share/apps/nepomuk nepomukserver
This will, of course, wipe out all the database, including any tags you've added. In theory, I understand that it's possible to do a more selective wipe of the database. If this matters to you you can find the instructions at this page
IMAP Resource always claims to be offline
Even though the system has an internet connection, the IMAP resource refuses to switch to online state.
This bug is caused by a misconfigured NetworkManager installation on your system. Check the output of
qdbus --system org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.state
If it is '4' (Disconnected) but you can access the Internet, then your NetworkManager is indeed configured wrong. If it is '3' (Connected) the problem must be somewhere else. Under Debian this behavior can be caused by interfaces defined in /etc/network/interfaces, which are not controlled by NetworkManager. To fix this, simply remove the entries from /etc/network/interfaces and let NetworkManager handle them.
Een aantal technische kwesties
Nepomuk
Starting with KDE 4.4, it is required that Nepomuk is running in order for Akonadi to work correctly. Akonadi will check this and display an error dialog on startup if this is not the case.
Nepomuk only works with the Virtuoso backend. You can check whether the Nepomuk is running with the correct backend by using the Akonadi self-test dialog, as described above.
Although Nepomuk is required to be running, you can still disable Strigi file indexing, which is usually the most resource-intensive part of the Nepomuk framework.
Apparmor
Some distributions using Apparmor have it set up in a way that prevents Akonadi from running its internal database server. This can result in a variety of fuzzy error messages, including but not limited to the following:
unknown error 255 when running akonadictl "DB error: 'Could not open required defaults file: /home/$username/.local/share/akonadi/mysql.conf"
You can solve this by running the following command with root privileges then reload apparmor:
aa-complain mysqld
In Kubuntu is dit:
sudo aa-complain mysqld sudo /etc/init.d/apparmor reload
Let op: wellicht gebruikt u Apparmor zonder dat dit zichtbaar is in de proceslijst.
Also note that some distributions ship an additional mysqld binary called mysqld-akonadi which has AppArmor set up correctly. If that's the case on your system and you see this problem nevertheless, there are two possible reasons:
- Akonadi still uses mysqld instead of mysqld-akonadi. You can change that in .
- AppArmor is not setup correctly for mysqld-akonadi either. Try running the "aa-complain" command noted above with mysqld-akonadi instead of mysqld.
---
You will also experience this problem if you are running an encrypted home directory using encryptfs combined with AppArmor as the Akonadi apparmor profile currently does not account for an ecrypted home (common with Ubuntu Jaunty users). Error messages with include:
- dmesg produces:
ecryptfs_do_create: Failure to create dentry in lower fs; rc = [-13] ecryptfs_create: Failed to create file inlower filesystem
- Akonadi geeft de volgende foutmeldingen:
Akonadi server process not registered at D-Bus
Dit is op te lossen door het bestand "/etc/apparmor.d/usr.sbin.mysqld-akonadi" aan te passen. Voeg onder de regel:
@{HOME}/.local/share/akonadi/** rwk,
Voeg een nieuwe regel toe:
@{HOME}/.Private/** rwk,
Herstart apparmor en herstart akonadi.
Ontbrekende voorwaarde
Om Akonadi te kunnen gebruiken, moeten de volgende packages geïnstalleerd zijn. Afhankelijk van uw distributie kunnen de namen anders zijn:
- De MySQL server (die heet mysql in openSUSE)
- Dee Qt4 MySQL plugin (die heet libqt4-sql-mysql in openSUSE)
If you compile Qt4 yourself, make sure to tell the configure script to build in MySQL support by passing it the following option:
-plugin-sql-mysql
If "configure" cannot locate the necessary MySQL client code (i.e, says "MySQL support cannot be enabled due to functionality tests") then ensure that the corresponding package is installed (typically called [lib]mysql[client]-dev[el]). Also, depending on the install location of the MySQL headers, additional parameters to "configure" might be needed (eg. "-I /usr/include/mysql" on OpenSuse).
Als u de Qt4 rechtstreeks van Nokia krijgt, zoals een download van qt-sdk-linux-x86_64-opensource-2009.05.bin</code, dan krijgt u een foutmelding bij Test 1 tijdens het uitvoeren van het commando "akonadictl start":
Database driver not found.
Details: The QtSQL driver 'QMYSQL' is required by your current Akonadi server configuration.
The following drivers are installed: QSQLITE.
Make sure the required driver is installed.
U hebt de driver libqsqlmysql.so nodig.
Helaas is deze driver is geen onderdeel van de distributie (tot januari 2010).
U moet de broncode compileren. Download dit bestand:
qt-everywhere-opensource-src-4.6.0.tar.bz
Then configure and make as above. But the make install doesn't copy the driver. So you have to copy it by yourself:
cp <qt-src-dir>/qt-everywhere-opensource-src-4.6.0/plugins/sqldrivers/libqsqlmysql.so /usr/local/bin/sqldrivers/
But the Revision 4.6.1, such as qt-sdk-linux-x86_64-opensource-2010.xx.bin has the driver you needed.
Omgeving instellen
The Akonadi server searches for Akonadi agents and resources in the paths defined in the XDG_DATA_DIRS environment variable. If Akonadi complains about not finding agents or resources, check if this variable is set correctly. Also keep in mind that even if set in a current console session, it might not have been set when starting the server. Starting the server manually in the current console session excludes this cause.
mysqld: unknown variable 'innodb_file_per_table=1'
Als het logboek van de MySQL server de volgende foutmelding bevat, dan is uw MySQL server gebouwd zonder ondersteuning voor InnoDB, wat nodig is om gebruik te maken van Akonadi, of InnoDB moet geladen worden in uw instellingenbestand mysql.conf:
[ERROR] /usr/libexec/mysqld: unknown variable 'innodb_file_per_table=1'
[ERROR] Aborting
Voeg toe:
#sql_mode=strict_trans_tables <- Add underneath this line
#plugins
plugin_dir=usr/lib/mysql/plugin < - This may be a different path
plugin-load=ha_innodb.so
Table 'mysql. servers' doesn't exist
Als het logboek van MySQL server de volgende foutmelding bevat, dan hebt u waarschijnlijk nog instellingenbestand voor MySQL:
[ERROR] Can't open and lock privilege tables: Table 'mysql.servers' doesn't exist
[ERROR] Cannot open mysql.db
[ERROR] Cannot open mysql.user
[ERROR] Cannot open mysql.event
Copy it from /usr/share/config/akonadi/mysql-global.conf into ~/.config/akonadi/mysql-local.conf. (For debian and openSuSE users the file is located in /etc/akonadi/mysql-global.conf). Then open it and uncomment the line sql_mode=strict_trans_tables. After that, you may get the following errors:
[ERROR] Plugin 'InnoDB' init function returned error.
[ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
[ERROR] Unknown/unsupported table type: innodb
[ERROR] Aborting
If so, then in the same file find the line that starts just like the one above (which you have uncommented), but has additional parameters, separated by commas (something like sql_mode=strict_trans_tables,strict_all_tables, ...etc). Comment the shorter sql_mode=... line and uncomment the longer one.
In openSUSE 11.2 lost de volgende opdracht het probleem op:
mysql_install_db --datadir=$HOME/.local/share/akonadi/db_data/
For Archlinux:
mysql_install_db --datadir=$HOME/.local/share/akonadi/db_data/ --basedir=/usr
Bijwerken naar Kubuntu 10.04 (Lucid Lynx)
This is a summary of other entries here for those upgrading from Kubuntu 9.10 to 10.04 who may have been using a personal package archive (PPA) for KDE 4.3 for bug fixes.
Install missing prerequisites. Remove previous akonadi cache. Start the akonadi service. Install the database. Upgrade the database. Stop and restart the akonadi service.
sudo apt-get install virtuoso-server mysql-server-5.1
rm -r $HOME/.local/share/akonadi
akonadictl start
mysql_install_db --datadir=$HOME/.local/share/akonadi/db_data/
mysql_upgrade --socket=$HOME/.local/share/akonadi/db_misc/mysql.socket
akonadictl stop
akonadictl start
De opdracht mysql_install_db levert een aantal foutmeldingen op die u kunt negeren:
Installing MySQL system tables...
100501 18:04:30 [Warning] Can't create test file

forum.kde.org Akonadi 1.2.1 - een paar problemen
KAddressBook upgraden
In addition to the Kubuntu 10.04 remedy above, problems trying to add a Vcard directory may require the following command while Akonadi is not running:
rm -rf $HOME/.config/akonadi
Can't initialize character set latin1
Als u de volgende foutmelding krijgt bij het starten van Akonadi, dan gebruikt u waarschijnlijk een versie van MySQL server met een versie hoger dan 5.1.42:
Character set 'latin1' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index.xml' file
Nepomuk QueryServer interface not available!
Connecting to deprecated signal

Character set 'latin1' is not a compiled character set and is not specified in
the '/usr/share/mysql/charsets/Index.xml' file
Database error: Cannot open database.
Last driver error: "QMYSQL: Unable to connect"
Last database error: "Can't initialize character set latin1 (path:

Database error: Cannot open database.
Last driver error: "QMYSQL: Unable to connect"
Last database error: "Can't initialize character set latin1 (path:
/usr/share/mysql/charsets/)"
Er is een bekende regressie in MySQL 5.1.43 en 5.1.44 waardoor MySQL niet kan worden gestart.
Zie de bugmelding voor meer details.
Herstarten na een eerdere fout
If you had problems starting Akonadi and fixed those (such as a missing package or the Apparmor problem) make sure that the Akonadi server is completely shut down before trying to start it again, by calling on the command line:
akonadictl stop
U kunt het afsluiten bevestigen door het uitvoeren van:
akonadictl status
Under some circumstances the Akonadi server can be stuck in a partially running state after a failure which will prevent the next attempt to start it to fail as well. Please file a bug report if you run into this problem including the self-test report of the initial problem.
De zogenaamde "Gentoo-Assert"
That's an especially nasty problem that so far only affects users of source-based distributions, most prominently Gentoo. It is named after MySQL assertions like the following example and is most likely caused by a MySQL protocol mismatch between the MySQL server and the client library or the Qt MySQL driver.
akonadiserver: libmysql.c:4301: setup_one_fetch_function: Assertion
`param->buffer_length != 0' failed.
It is extremely hard to diagnose as the assertion mentioned above is only triggered sometimes. Instead you'll get a wide range of weird symptoms:
- ASAP protocol logs show successful creation of objects which are supposedly no longer available when the next commands access them again.
- SQL protocol logs show INSERT or UPDATE commands with values that mismatch the corresponding column types and nevertheless succeed.
- SQL protocol logs showing large apparently random record ids which are nevertheless considered valid.

Mogelijke oplossing: bouw de Qt MySQL driver opnieuw na het upgraden van MySQL. MySQL is sowieso de meest waarschijnlijke oorzaak van dit probleem.
