As already said, this was due to configuration of my machine

The key message is:

you are using pam_tally or pam_tally2 in your configuration
The pam_tally and pam_tally2 modules have been removed from PAM. You are using one of these
modules in your PAM configuration in /etc/pam.d. You must remove the uses of these modules
before PAM can be upgraded; including these modules in your PAM configuration after the upgrade

You have to remove the links to pam_tally and pam_tally2 from your /etc/pam.d configuration files (end eventually replace them by pam_faillock). Then you can re-try the install/update of the new pam package.

What is the output of the command
grep tally /etc/pam.d/*

Thanks I figured it out afterwards, and changed the configuration.
As I already marked on the question as well.
The problem was that it was in the middle of do-release-upgrade, so all the process have been stopped, but it could have been changed somehow so that the process will not be stopped.
As the do-release-upgrade have been stopped completely, I had to do the upgrade manually from there on.

Nothing impossible but, some supplementary steps not to forget as well.
