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?
