mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)
sudo dpkg ––configure –a doesn't work either.
I cannot install any package.
Question is different from mysql-server-8.0 installation problem on Ubuntu 20.04 because I absolutely cannot install mysql-server. He managed to install it. And my package manager broke on installing it, so I can't install or remove anything now.

Boot the system into recovery mode and run dpkg which should repair the broken packages.
