Hi I've been having some problems lately with starting mysql in Ubuntu-22.04.
When i try sudo service mysql start an error pops up:
Failed to start mysql.service: Unit mysql.service failed to load properly, please adjust/correct and reload service manager: File exists
See system logs and 'systemctl status mysql.service' for details.
I've also tried some "fixes" from stackoverflow and other forums but none of them seemed to work mainly because of the autoremove part.

Any ideas?
Try uninstalling and installing the server like this:
sudo apt-get clean
sudo apt-get purge mysql*
sudo apt-get update
sudo apt-get install -f
sudo apt-get install mysql-server-8.0

do: sudo apt edit-sources and look for anything containing mariadb like: deb [arch=amd64,arm64,ppc64el] http://ftp.nluug.nl/db/mariadb/repo/10.3/ubuntu bionic main
comment it out by putting a # in front of it. then run
sudo apt update
sudo apt purge mysql-common
sudo apt install mysql-common
after that you can installed mysql-server properly via sudo apt install mysql-server
Helped me fix the issue.

and I can not re install mysql , what can I do , I looked for solution but don't have result
Try doing a purge, then re-install.
sudo apt-get remove --purge mysql-\*
sudo apt-get install mysql-server mysql-client
When logging in through mysql -u root -i, I get the following error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
I've tried sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-5.5, I've auto removed, cleaned, removed all associated files. After all that, I did a sudo apt-get remove --purge mysql* just to be safe. Then I installed it again: sudo apt-get install mysql-server
I get an error during the installation:

I'm not really sure what else I can do.
So I guess the purge and installation worked. On one last whim, I decided to reboot my BeagleBone and try again. It worked.
I have been unsuccessful at installing a mysql server on Ubuntu 12.04. Here is what I see when I try to install after a remove --purge of mysql server:

A mysql client is installed, but when I try to launch it I get this:

Any help will be appreciated.
Well, I got no help from StackExchange, so I dug deeper and figured it out myself: First I got rid of mysql-server and mysql-client by following instructions at Removing MySQL 5.5 Completely. Then I simply installed the server and client as usual with apt-get. Everything worked fine after that.
I'm running a Wordpress installation on an Ubuntu 12.10 server. The site was running fantastically until we had sporadic MySQL issues, where the site would "whitescreen" for a few hours, then return to normal.
Someone who should not have been toying around with the server removed MySQL to attempt a reinstall, and now mySQL refuses to reinstall. I get the following errors when running sudo apt-get install -f mysql-server from root.

In addition, I couldn't connect to MySQL through the socket before this all happened.
Things I've tried, as recommended here/on other websites:
Restarting mysqld Deleting and (attempting) reinstallation of mysql-server
deleting all files shown when running dpkg -S etc/mysql
apt-get purge mysql-server mysql-client mysql-common mysql-client-5.5 mysql-server-5.5
apt-get auto cleans
apt-get with the -f flag
Numerous server reboots and restarts
Tears
Have you tried entering this through terminal/PuTTy?
apt-get install mysql-server mysql-client
