I’m having trouble to upgrade an installation of 5.7.20 to 5.7.21 on a Ubuntu 16.04 system. Upgrade fails with pre-installation script error but I wasn’t able to debug it. After failing to upgrade system asks to execute “apt-get install -f” but this fails also.

Any hints on where to look or what to try?
Thanks in advance.
