Public bug reported: #1968154 removed `/etc/kernel/postinst.d/apt-auto-removal` in this patch: https://git.launchpad.net/ubuntu/+source/apt/commit/?id=f9d2d993687c0d5223c241956ef6a0aabcf15bf0
...but `apt.postinst` still tries to run it: # create kernel autoremoval blacklist on update if dpkg --compare-versions "$2" lt 0.9.9.3; then /etc/kernel/postinst.d/apt-auto-removal fi If I understand correctly, "$2" is the most-recently-configured-version, and if it's empty `dpkg --compare-versions lt` will evaluate to true. This fails when I'm building a focal (20.04) userspace from scratch: $ dpkg --configure -a [...] Setting up apt (2.0.8) ... /var/lib/dpkg/info/apt.postinst: 65: /etc/kernel/postinst.d/apt-auto-removal: not found dpkg: error processing package apt (--configure): installed apt package post-installation script subprocess returned error exit status 127 It works with apt 2.0.6. ** Affects: apt (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1974456 Title: regression: apt.postint fails if never previously configured To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1974456/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
