Redmine worked perfect then this error in the middle of the day

sorry redmine 15.0

looking around looks like mysql/mariadb does  not start complains about the /var/rus/mysql.sock that does not excist??? now i worry!!!?

Please see the blog post I put up a couple of days ago for a workaround/fix. FWIW I sent out an email notification immediately after posting that.

Once reinstalled, MariaDB functionality should return to normal.

Also @Thys, I just checked your user account and it seems that you've been signed up for ages and are subscribed to the "security and news announcements" so you should have got an email notification about that a couple of days ago?! I suggest that you check your spam folder and/or your email settings as you should have received the email.

root@redmine ~# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")
root@redmine ~# mariadb
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")

I've just opened another topic, but the issue is the same. A debian security update killed MariaDB.

I can create a new VM with MariaDB and make it work after removing and reinstalling MariaDB, but the existing ones are dead. Can't make backup of the database because it only works if we clean the data directory.

Thanx a million Jeremy your fix (update and re-install of mysql/mariadb) worked 100% ...

Whilst this likely won't make much difference to you good people, I'd thought it worth mentioning that we have now updated all of our appliance images, including Redmine so this fix should now no longer be required on fresh appliance installs.
