I just tried to install ubuntu 11.10 (from 11.04). All the packages have been downloaded, and installed. But in the end (before cleaning up), a window popped up: Could not install the upgrades: The upgrade has aborted. Your system could be in an unusable state. A recovery will run now .... Then the installation has exit. I manually restarted the computer, visually I am using now ubuntu 11.10. But still the resting stages of installation cleanning up has not been run.

Does anyone know if it is normal? What should I do to amend that?

Thank you!

what happens if you run sudo apt-get update && sudo apt-get dist-upgrade ? – fossfreedom Oct 16 '11 at 21:05

From your pastebin trace it looks like you have readded a pidgin PPA. There is no oneiric version of this PPA - so my advice is to open your software sources and untick this PPA.


Open the Dash (click the top icon in the launcher) and search for "software"

enter image description here

Then find the pidgin PPA and untick it in this tab:

The rest of the trace shows that you have successfully upgraded to oneiric.


sudo apt-get update && sudo apt-get dist-upgrade

Ensure you have no further errors. Then you can cleanup outstanding packages that you no longer need and is just taking up disk-space.

sudo apt-get autoclean
sudo apt-get autoremove
