Ubuntu – How to solve GNOME power manager installation problem


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.

Best Answer

The error message you are probably getting is

Install Problem! The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator.

This likely happens after a release upgrade

To fix it, press Ctrl+Alt+F1 on the login screen and login with your username and password and type these commands

sudo apt-get clean
sudo apt-get autoclean

It should probably fix it. The error is most likely caused due to lack of space

If the above doesn't work, you can try chmodding /tmp to 0777.

chmod 0777 /tmp
