Hello, isc-kea-common 1.6.1-isc0042520191119145256 is not an ubuntu package. I believe that came from upstream. The debian/ubuntu packages do not have the "isc-" prefix.
https://kb.isc.org/docs/isc-kea-packages says: """ Package Names We have labelled all of our packages "isc-kea" to keep installation from over-writing existing packages you may have from another source """ Indeed, https://cloudsmith.io/~isc/repos/kea-1-6/packages/ (linked from above) contains isc-kea-common which contains isc-kea-common 1.6.1-isc0042520191119145256 That being said, the debian package used to remove the user in postrm, but stopped doing that in 1.5.0-2: isc-kea (1.5.0-2) unstable; urgency=medium [ Jason Guy ] * Stop deleting _kea user and group on postrm for security Purging it works fine in focal, but I'm still seeing these: Purging configuration files for kea-common (1.6.2-0ubuntu1) ... dpkg: warning: while removing kea-common, directory '/var/log/kea' not empty so not removed dpkg: warning: while removing kea-common, directory '/var/lib/kea' not empty so not removed For which I will file a bug, once I double check the debian policy that these contents (logs and lease files) should be removed on purge. ** Changed in: isc-kea (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863410 Title: Old isc-kea-common package removal looks dangerous To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-kea/+bug/1863410/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
