[Solved] Chicken and egg issue with Mariadb?
Hello to all,
An upgrade of Mariadb did not go well (or more probably, I failed to run a mysql_upgrade -u root -p before rebooting).
Consequence: I am now unable to start mariadb.service:
gilgamesh@uruk ~ $ sudo systemctl start mariadb.service
Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xeu mariadb.service" for details.
When I try to see the log, I got mostly the following error message:
'mysql.plugin' doesn't exist". Some plugins may be not loaded
I thus went under archlinux wiki, and apply the guidelines on the Mariadb "troubleshooting" section:
gilgamesh@uruk ~ $ sudo mysqld_samysqld_safe --datadir=/var/lib/mysql/
220828 14:46:53 mysqld_safe Logging to '/var/lib/mysql//uruk.err'.
220828 14:46:53 mysqld_safe Starting mariadbd daemon with databases from /var/lib/mysql/
gilgamesh@uruk ~ $ sudo mysql_upgrade -u root -p
Enter password:
Reading datadir from the MariaDB server failed. Got the following error when executing the 'mysql' command line client
ERROR 2002 (HY000): Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)
FATAL ERROR: Upgrade failed
I tried as well a reinstall of mariadb, without any improvement of the situation.
And there I am stuck. I have the feeling to be trapped in some kind of chicken and egg issue, where we need to have mariadb running to be able to run the mysql_upgrade stuff, but at the same time need to run the mysql_upgrade command to be able to launch the service...
To be noted I have this issue on a up-to-date Archlinux version.
Thanks.

Just
downgrade
mariadb, run the
mysql-upgrade
command and then update.
No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Does that socket exist? If so, run `stat` on it and report the results here.

Re: [Solved] Chicken and egg issue with Mariadb?
After deep-diving the case on the net, I came to the conclusion that the database was most probably corrupted.
So I removed the ib* file in /var/lib/mysql, and reinstalled Mariadb, which solved the issue.
Had to reinstall Akonadi as well and reimport all my emails into Kmail, but that's no big deal.
Thanks to the people sharing some tips and help.
