Confirming issue exists on Kubuntu 20.04.4 LTS. Every attempt to login from the graphical login screen makes this error appear in authlog:
/var/log/auth.log:Apr 27 13:56:16 <hostname> kcheckpass[3516]: pam_ecryptfs: seteuid error Quick "fix" of the symptom, i.e. make the error go away is to add the seteuid-bit permission to kcheckpass (owned by root): sudo chmod u+s /usr/lib/x86_64-linux-gnu/libexec/kcheckpass However, this seems like a too broad privilege grant so I'm not sure it is a good idea. Personally, I prefer to have the spurious error in the log over this broad privilege grant. Note that login succeeds despite the error appearing in authlog. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1085706 Title: pam_ecryptfs: seteuid error To manage notifications about this bug go to: https://bugs.launchpad.net/ecryptfs/+bug/1085706/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
