Re: broken packages and unfulfilled dependencies

Ok I see, what you'd posted was a laughable Google mistranslation.

Something's gone sideways with your repo.

If there's existing MySQL data you wish to keep, do a complete backup with mysqldump.

Then this has been recommended for such situations. As root, execute ...

apt-get autoremove
apt-get autoclean

apt-get purge mysql-server
apt-get purge mysql-common
rm -rf /var/log/mysql
rm -rf /var/log/mysql.*
rm -rf /var/lib/mysql
rm -rf /etc/mysql

Then ...

apt-get dist-upgrade

and then, apt-get install or update as your situation requires; with the cmd include --fix-missing --fix-broken

May also need ...

apt install mysql-community-client-plugins mysql-common
