Package: getmail6 Version: 6.11-1 The getmail source and binary packages have been removed from Debian[1]. To facilitate upgrades from Buster, src:getmail6 should take over the getmail binary package, otherwise its users will either be left with an unsupported obsolete package or with nothing at all, depending on what apt decides to do during the dist-upgrade to Bullseye.
