I am using Ubuntu 12.10. I tried to upgrade it using the Software Updater, but it is not working even after pressing Upgrade button. Then I tried to upgrade through the terminal using the command sudo apt-get upgrade. I got the following error message:

sudo: unable to change to sudoers gid: Operation not permitted.  

Please help.

  • Thanks for your cooperation. Surprisingly when I opened the computer yesterday night, it is found that everything was fine and upgrading to 13.04 was also done without any hindrance. I think there was internal problem in 12.04 itself. Oct 9, 2013 at 7:20

You may have to upgrade through downloading the ISO for 13.04 and burning it to a DVD. I had a similar problem long ago and that was the only solution.

It shouldn't delete your personal data, but always backup!
