Splash screen shows Ubuntu 23.10 instead of 24.04 and forces logout

[Richard M]

We performed a minimal install of Ubuntu Server 24.04, disabled swap. This is a machine with limited resources (8GB SSD, 2GB RAM).

Installed ubuntu-desktop-minimal, stopped/disabled/removed gdm3; installed lightdm and rebooted.

After reboot we see the maroon X splash asking us to login. However at the bottom right of the screen it says "Ubuntu 23.10", not "Ubuntu 24.04".

When we login by entering the password we get a white screen with a sad face icon and the words:
"Oh no! Something has gone wrong. A problem has occurred and the system can't recover. Please log out and try again." Trying again results in the same problems.

The above set of install steps works fine using the Ubuntu Server ISO for Ubuntu 22.04.4.
