Bug 482442

Similar problems. Fresh install. Installed kmail, had to manually install akonadi-backend-mysql. Akonadi still won't start.

$ akonadictl start
org.kde.pim.akonadictl: Starting Akonadi Server...
org.kde.pim.akonadictl:    done.

Tried sudo aa-complain /usr/bin/akonadiserver and got the error "ERROR: Include file /etc/apparmor.d/local/mariadbd_akonadi not found"

Currently stuck. :)

Seems this bug had a similar error (Permission denied): https://bugs.kde.org/show_bug.cgi?id=427618

In trying to invoke mysqld directly:

$ /usr/sbin/mysqld --defaults-file=/home/jkugler/.local/share/akonadi/mysql.conf --datadir=/home/jkugler/.local/share/akonadi/db_data/  --socket=/run/user/1000/akonadi/mysql.socket --pid-file=/run/user/1000/akonadi/mysql.pid

MariaDB starts and runs without issue.

In /etc/apparmor.d/, I ran:

sudo aa-complain ./mariadbd_akonadi
sudo aa-complain ./mysqld_akonadi

Akonadi is up and running now.

have fixed a packaging error which should mean that all the apparmor files are installed.  building now but plasma 6.0.1 just started as well so could take a while - https://invent.kde.org/neon/kde/akonadi/-/commit/2ebb2156dda19bed3d0795d95fa24a78e32193b6

hhhmmm no.  that actually made it worse.  reverted.  investigating the nuances of dh_apparmor and why it isn't working correctly

Since an update some time ago, it started working again. If no one is against it, I would suggest closing this as fixed.

Same here:  Freshly installed neon user 20240614-1438 + all updates.   Copied my old $HOME to the new installation. Installed kmail, korganizer and akonadictl start fails with 'Failed to detect mysqld version!'

Touching missing files aa-complain  complains about does not help:

Setting /etc/apparmor.d/usr.bin.akonadiserver to complain mode.

After touching the 2 missing files aa-complained about + 

   systemctl reload apparmor.service

Now **akonadictl start** works :-)

Bumping this, I just found out the hard way that I have to touch those files before apparmor will run with the installed akonadi_mysql and akonadi_mariabdb config files.

System versions:
Operating System: KDE neon 6.2
KDE Plasma Version: 6.2.3
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0

Just installed the latest Neon User image on a machine and still had this problem. Had to touch

/etc/apparmor.d/local/mysqld_akonadi
and
/etc/apparmor.d/local/mysqld_akonadi

Then:
systemctl reload apparmor.service

aa-complain usr.bin.akonadiserver 

And it worked.
