Hi, sorry that you hit this problem. From the information provided, I couldn't figure out what exactly is wrong.
I would suggest that you try the following: sudo apt -f install The only relevant thing that libpam-sss does in postinst is to call: pam-auth-update --package If that's what is failing, that's something that can be further investigated. ** Changed in: sssd (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2092654 Title: package libpam-sss:amd64 2.9.4-1.1ubuntu6.2 failed to install/upgrade: installed libpam-sss:amd64 package post-installation script subprocess returned error exit status 128 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sssd/+bug/2092654/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
