Please, run sudo dpkg --audit or sudo dpkg -C, it's the same. It probably will suggest to you what to do.
Edit: According to your comment,
Setting up mysql-server-5.7 (5.7.29-0ubuntu0.18.04.1) ... update-alternatives: error: alternative path /etc/mysql/mysql.cnf doesn't exist dpkg: error processing package mysql-server-5.7 (--configure): installed mysql-server-5.7 package post-installation script subprocess returned error exit status 2 Errors were encountered while processing: mysql-server-5.7
the update-alternatives program failed to find this mysql.cnf file.
Could you try creating that file?
Please, do:
sudo nano /etc/mysql/mysql.cnf
filling with this content:
[mysql]
Then, try again dpkg --configure <package>
Or, this will probably do the job:
sudo apt-get remove --purge mysql-\*
sudo apt-get install mysql-server mysql-client
If interested, you could also read A Quick Guide to Using the MySQL APT Repository. They provide different installation approaches for different scenarios.

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

Also purging causes the same error
you may try to remove package manually
su -c 'dpkg - P -remove --force-all mysql*'
then you need to rebuild rum database
su -c 'apt-get clean all && rpm --rebuilddb'
su -c 'package-cleanup --problems'
Edit
to backup all your databases
mysqldump -u USER -p --all-databases > /mnt/backups/all_databases.sql

I am absolutely stumped at this point...
As discussed earlier in the discussion in the post, I think you are safe to reinstall it. We should remove all traces of previous installation of mysql and then reinstall it.
sudo apt-get remove --purge mysql*
If these were installed as part of the package dependencies for mysql,
sudo apt-get autoremove
sudo apt-get autoclean
Then the important bit, this error could be caused because your distribution is not upgraded recently, or at least conflicts are not resolved properly. I would just upgrade Ubuntu.
sudo apt-get dist-upgrade
Now after this is done, you can try to install mysql as normal again. Hope this will work, please give a report. If it doesnt work we'll try another fix.
Here's a link to digital oceans installation for mysql. Though you could use MariaDB.

A mysql client is installed, but when I try to launch it I get this:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
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.
