Hi, Andreas. The Debian/Ubuntu "upgrade-system" package automates updating the APT package list, installing updated packages and removing 'orphaned' packages. It is very convenient for unattended upgrades of multiple computers because it can either be run interactively, or without a controlling terminal. The "upgrade-system" config file is: /etc/upgrade-system.conf By default, "upgrade-system" allows "deborphan to 'guess' which packages to remove: ORPHANOPTS="--guess-all --libdevel" This removes too many packages that are installed by "med-bio-dev' in particular, so I edited the config file to stop "deborphan" guessing: ORPHANOPTS="--no-guess-all --libdevel" It appears that a recent upgrade unconditionally overwrote my edited "upgrade-system.conf", which resulted in most of the packages installed by "med-bio-dev" being removed from five of my bioinformatics servers. Yes, it is a user's responsibility to check but I was caught out by it recently so I posted a bug report because I thought other people might also have the same problem when using "upgrade-system" with defaults. The "upgrade-system" package is very convenient, but the default settings allow "deborphan" to guess what to remove. In my experience, that often results in "deborphan" removing packages that are needed.
