Akonadi don't start - Failed to remove Unix socket / runtime connection config file

[wired2051]

Yesterday my PC goes Hibernate (StD), what is normally no problem, and after that Kontact doesn't work any more. Kontact- and Kubuntu-restart made no difference. Today morning Kontact says after booting Can't connect to local MySQL server through socket 'tmp/akonadi-USER.eCmOAU/mysql.socket' (111) QMYSQL.

This is the akonadi-status back than:

USER@RECHNER:~$ akonadictl status

Now, after several hours, I started Kubuntu again and Kontact only says Akonadi doesn't work correctly but offers no Details.

This is the Akonadi-Status after Kontact tries to start Akonadi now:

USER@RECHNER:~$ akonadictl status

When I try to start Akonadi manually it says:

If I cancel with strg-c, Akonadi Control: stopped and Akonadi Server: stopped

~/.local/share/akonadi/akonadiserver.error isy quite short:

Database process exited unexpectedly during initial connection!

What can I do other than reset Akonadi by deleting all files/folders?

I solved the issue with these steps: Created the folder: sudo mkdir /var/lib/mysql-files Started the service: akonadictl start Purged and reinstalled Kontact: sudo apt purge kontact && sudo apt install Kontact Start Kmail Hope this helps. Regards.

[wired2051]

Thanks for your fast respond!

/var/lib/mysql-files already exists so I skipped the mkdir.

That looks not good to me so I also skipped apt purge.

Then maybe your last update didn't update properly.
Repeat these two commands until no error msg is reported, if any are.
sudo apt install -f
sudo dpkg -configure -a

[wired2051]

Mmmmh. Month after update from 14. 04 to 16.04?

I'm a little bit nervous doing changes in the packet-installation, so I wonder what -f in apt install -f is doing?

Man pages were written so that we don't have to wonder:
man apt-get

[FONT=monospace]
       [COLOR=#000000][B]-f[/B][/COLOR][COLOR=#000000], [/COLOR][COLOR=#000000][B]--fix-broken[/B][/COLOR]
           Fix; attempt to correct a system with broken dependencies in place. This option, when used with install/remove, can omit any packages to
           permit APT to deduce a likely solution. If packages are specified, these have to completely correct the problem. The option is sometimes
           necessary when running APT for the first time; APT itself does not allow broken package dependencies to exist on a system. It is possible
           that a system's dependency structure can be so corrupt as to require manual intervention (which usually means using [COLOR=#000000][B]dpkg[/B][/COLOR][COLOR=#000000][B]--remove[/B][/COLOR][COLOR=#000000] to[/COLOR]
           eliminate some of the offending packages). Use of this option together with [COLOR=#000000][B]-m[/B][/COLOR][COLOR=#000000] may produce an error in some situations. Configuration Item:[/COLOR]
           APT::Get::Fix-Broken.

[/FONT]

The two commands together most often clear up incomplete or broken installs, updates, etc...

In your case it may not help but it is an easy thing to do.

Man pages were written so that we don't have to wonder:
man apt-get

OK, that's my fault. I looked up apt, not apt-get. I confess, the package-management is one of my weak points.

My typo. The command should have been
sudo dpkg --configure -a
(two dashes, not one, in front of "configure", one dash in front lf "a"

The other problem is probably an intermediate file that wasn't deleted for some reason (failed installation of a package?). Delete it and run the two cleanup commands again until they return no errors or the error doesn't change.

But this doesn't help. Kontact doesn't start.

You might install akonadiconsole and explore akonadi to see what is what. That's what I used to get akonadi running last year.

You could also purge akonadi and reinstall it.

[wired2051]

First: I appreciate your patient willingness to help!

I'm not used to the Akonadi Console but if I start it, it says twice Can't connect to local MySQL server through socket 'tmp/akonadi-USER.eCmOAU/mysql.socket' (111) QMYSQL before it starts. Then, it can't start akonadi. I also can't start akonadi:

[wired2051]

You could also purge akonadi and reinstall it.

I'm always unsure using the package management, so I have to ask (I even not know the different between apt and apt-get):

akonadictl stop
sudo apt purge akonadi
sudo apt install akonadi

Is this the right way? No options required?

I read after apt install the package is marked as "manually installed", is this a problem?

Those commands are correct. What happens afterwards depends on dependencies.

Manually installed means that you didn't install it via the package manager. It doesn't matter.
I am curious as to why your tmp file has "-USER-" in it and not your account name. Here is mine:


Notice the folder name and its contents. Sockets are empty files, since everything in Linux HAS to be a file. MySQLID contains the PID of MySql.

[wired2051]

USER is correct (next time I think about it before I'm choosing a user name). The folder exists but is empty. Is this because akonadi is not running for some days now?

This is my simulation of purge:

USER@RECHNER:~$ sudo apt purge -s akonadi

E: Paket akonadi kann nicht gefunden werden.

[GreyGeek]

It's probably called akonadi-server.
