How can I completely uninstall mysql-server and reinstall?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I recently upgraded from 12.10 to 16.04 on my server. After upgrading (which appears to have gone fine), I was unable to login to my mysql server. As such, I uninstalled the server, and reinstalled using:
apt-get remove mysql-server
apt-get install mysql-server
However, now it always seems to give me:
Renaming removed key_buffer and myisam-recover options (if present)
initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused
insserv: warning: script 'screen-cleanup' missing LSB tags and overrides
insserv: Default-Start undefined, assuming empty start runlevel(s) for script `screen-cleanup'
insserv: Default-Stop undefined, assuming empty stop runlevel(s) for script `screen-cleanup'
Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
invoke-rc.d: initscript mysql, action "start" failed.

I tried stopping the service, uninstalling, purging, and even removing /etc/mysql and /var/lib/mysql (after backing up, of course).
I'm at a complete loss as to why this is happening now. I can't seem to recover my database data. I've noticed that whenever I do this uninstall/reinstall procedure, it's not asking me for a mysql password, so I wonder if it's not completely uninstalled.

Even trying to uninstall gives this error. It seems the package is in a weird state.

To remove all config files use
apt-get purge mysql-server*
rm -rf /etc/my.cnf /etc/mysql
If you want to delete all databases as well, you need to delete the directory /var/lib/mysql, too.
