Public bug reported: Unfortunately 26.04 inherited this bug from Debian: https://bugs.debian.org/1129522
Demonstration: podman run -it --rm docker.io/ubuntu:26.04 sh -exc 'cat /etc/nsswitch.conf; apt update; apt install -y libsss-sudo; cat /etc/nsswitch.conf' Initially, nsswitch.conf has no "sudoers:" entry, and after that it has sudoers: sss This is missing "files", thus any attempt to run "sudo" by users in the "sudo" or "admin" groups fails. The cause of this is that the postinst script adds "sss" to the end of "sudoers:" and assumes that "files" is already there. This was proposed in base-files but not yet in the distribution: https://bugs.debian.org/770825 PackageVersion: libsss-sudo_2.12.0-1ubuntu5_amd64.deb DistroRelease: Ubuntu 26.04 ** Affects: sssd (Ubuntu) Importance: Undecided Status: New ** Tags: regression-release resolute -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2151950 Title: libsss-sudo: Can't sudo after installing libsss-sudo (due to broken nsswitch update) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sssd/+bug/2151950/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
