I installed my updates today and now I can't login due to a fault. After booting, the login screen and the message about installation fault for GNOME power manager appears. After logging in, the system returns to the login screen again with the error message. I tried to boot using older kernel versions, but the same error appears. How do I solve this problem?
The exact error message is:
GNOME power management is not configured properly, and ask the Administrator to fix it.
