Help with User Authentication after Upgrading to 24.04.1

  • 772

I tried to upgrade from 22.04, and it successfully upgraded. The only problem, and it's a huge one, is that I cannot login, I get an incorrect login, authentication error, sorry try again. This happens when I want to enter the password of my users. I can not use sudo, cannot switch to root using su or sudo -i.

I can go to recovery and work as a root, though, so I tried changing passwords, but it did not fix the problem. I checked /etc/pam.d/sudo and /etc/shadow, checked locale and caps, all seem fine.

What else could be the problem? I am under the impression that polkit could be the reason, but I have no clue whatsoever how to check that. Appreciate any ideas

    I managed to fix the problem by copying /etc/pam.d/ directory from my Ubuntu 22.04 backup. I didn't bother to check which files were specifically modified by the upgrade process. So I just overwrote the whole directory.

    Now I have a fully functional Ubuntu 24.04.1 up and running 😀
