Found some version mismatches related to the vim-gtk package in /var/log/dist-upgrade/apt.log After removing all the packages related to vim, the upgrade was able to proceed. I will install vim again after the upgrade process is completed. I don't know whether this is a bug or not, but my workaround worked.
