Unable to install mysql-server, apt-get stuck at "Setting up".

[Dawid Wróbel]

I was trying to install mysql-server today and it stucks at "Setting up mysql-server-5.5 (5.5.22-0ubuntu1) ...".
A quick look at syslog shows that init loops mysql start infinitely:
"Apr 26 12:52:34 mele kernel: [75108.410000] init: mysql post-start process (26701) terminated with status 1
Apr 26 12:52:36 mele kernel: [75110.880000] init: mysql main process (26751) terminated with status 1
Apr 26 12:52:36 mele kernel: [75110.900000] init: mysql main process ended, respawning"

This seems to be caused by the following error:
"Apr 26 12:35:31 mele mysqld_safe[9500]: ERROR: 1050 Table 'plugin' already exists
Apr 26 12:35:31 mele mysqld_safe[9500]: 120426 12:35:31 [ERROR] Aborting

I am also getting similar problem. I don't how to get rid of it. Any workaround ? I am stuck with my activities.

Sakthivel, please mark at the top of the page that this bug also affects you, so it will be automatically marked as "confirmed" and prioritized.

For Ubuntu 12.04 and mysql-server-5.5

My 'work-around' was to replace mysql-server-5.5.postinst in /var/lib/dpkg/infor with the file of the same name from the SOURCE distribution ( was in mysql-5.5-5.5.22/debian/ )

Then the 'apt-get install mysql-server' ran successfully....

My additional problem for the new 12.04 machine was that 'start mysql' would fail.... This turned out to be a missing 'proc' file in /etc/apparmor.d/tunables. I copied the file from a 10.04 machine to the 12.04 machine and all is well

[Dawid Wróbel (dawidw)]

Simon, please mark the bug as affecting you so it gets automatically the "confirmed" status and a chance to be resolved by a package upgrade.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Removing apparmor package solves the problem, please fix apparmor profile:

mike-nycmoma, you saved my life. This is a crazy bug and I was about to destroy everthing...

In my case, apparmor isn't even installed, so it can't be removed. Still,

  Setting up mysql-server-5.5 (5.5.60-0+deb8u1) ...

is hanging...

[Andreas Hasenack (ahasenack)]

We are sorry, but it looks like this bug fell through the cracks and was forgotten. Since Ubuntu 12.04 is no longer supported, I'm going to mark this issue as "won't fix".

If it's still happening in a supported version of Ubuntu, then please reopen this bug stating the new information. Thanks.
