Akonadi Server Self-Test Report
===============================

Test 1:  SUCCESS
--------

Database driver found.
Details: The QtSQL driver 'QMYSQL' is required by your current Akonadi server configuration and was found on your system.

File content of '/home/stuart/.config/akonadi/akonadiserverrc':
[%General]
Driver=QMYSQL

[QMYSQL]
Name=akonadi
Host=
Options="UNIX_SOCKET=/tmp/akonadi-stuart.3lRYnN/mysql.socket"
ServerPath=/usr/sbin/mysqld-akonadi
StartServer=true

[Debug]
Tracer=null


Test 2:  SUCCESS
--------

Akonadi is not running as root
Details: Akonadi is not running as a root/administrator user, which is the recommended setup for a secure system.

Test 3:  SUCCESS
--------

MySQL server found.
Details: You have currently configured Akonadi to use the MySQL server '/usr/sbin/mysqld-akonadi'.
Make sure you have the MySQL server installed, set the correct path and ensure you have the necessary read and execution rights on the server executable. The server executable is typically called 'mysqld'; its location varies depending on the distribution.

Test 4:  SUCCESS
--------

MySQL server is executable.
Details: MySQL server found: 161109  2:41:53 [Warning] Using unique option prefix key_buffer instead of key_buffer_size is deprecated and will be removed in a future release. Please use the full name instead.
/usr/sbin/mysqld  Ver 5.5.53-0ubuntu0.14.04.1 for debian-linux-gnu on i686 ((Ubuntu))


Test 5:  SUCCESS
--------

No current MySQL error log found.
Details: The MySQL server did not report any errors during this startup. The log can be found in '/home/stuart/.local/share/akonadi/db_data/mysql.err'.

Test 6:  SUCCESS
--------

MySQL server default configuration found.
Details: The default configuration for the MySQL server was found and is readable at <a href='/etc/akonadi/mysql-global.conf'>/etc/akonadi/mysql-global.conf</a>.

Test 9:  SUCCESS
--------

akonadictl found and usable
Details: The program '/usr/bin/akonadictl' to control the Akonadi server was found and could be executed successfully.
Result:
Akonadi 1.12.91


Test 10:  ERROR
--------

Akonadi control process not registered at D-Bus.
Details: The Akonadi control process is not registered at D-Bus which typically means it was not started or encountered a fatal error during startup.

Test 11:  ERROR
--------

Akonadi server process not registered at D-Bus.
Details: The Akonadi server process is not registered at D-Bus which typically means it was not started or encountered a fatal error during startup.

Test 12:  SKIP

Protocol version check not possible.
Details: Without a connection to the server it is not possible to check if the protocol version meets the requirements.

Test 13:  ERROR
--------

No resource agents found.
Details: No resource agents have been found, Akonadi is not usable without at least one. This usually means that no resource agents are installed or that there is a setup problem.

Linux Mint 17.2 Rafaela
I have tended to do updates maybe once a week or fortnight. I'm not sure as to which update may have caused Akonadi to stop working.

my distribution is debian 8.
kmail started to fail immediately after I installed the lsb-core package as requested by message of apt-get dist-upgrade to make operative google-earth.
Comment 6 Daniel Vrátil 2016-11-18 13:35:01 UTC
This is a known issue with MySQL and certain distribution setups.

You can workaround it by creating a file ~/.config/akonadi/mysql-local.conf with the following line:

secure_file_priv=



(yup, there's nothing after the "=")

Then MySQL should start as expected.

Thanks Daniel, I tried but this does not work for me. I have have also updated the system (apt-get dist-update has detected some update for akonadi), but without effects (kmail always returns the same error as before).

Same report for me on KDE 5, Kubuntu 16.10 up to date.
Daniel's workaround not worked for me either.

Using "aconadictl start" gives me :
titi@TiTi-MSI-GT70-2OC:~$ sudo akonadictl start
Starting Akonadi Server...
   done.

Comment 9 Etienne 2016-11-27 23:13:30 UTC
Found DENIED access reports in Syslog so I disabled mysqld-akonady profile in AppArmor.
Found /var/lib/mysql-files not found trying to start "/usr/sbin/mysqld-akonadi --defaults-file=/etc/xdg/akonadi/mysql-global.conf --initialize --datadir=/home/titi/.local/share/akonadi/db_data/" manually
Installed mysql-server

Finally got an Unknown Error... Don't know where to look further.
