I recently installed Ubuntu 22.04 on a laptop and something weird happened to my password. I can only use it to login when I select a user (the booting GUI) and after that, things like sudo or password pop-ups don’t work (the system claims I provide a wrong password). Some other observations:
- the user is a member of the sudo group (
groups) - login as the root user doesn’t work either (
su -), the only option here is the recover mode where the root’s password works - it happens for every new user I create (using the recovery mode) – new users work normally for a while then the problem reoccurs
- neither x11 nor wayland works
passwd(recovery mode) doesn’t help
