I did a do-release-upgrade to upgrade from my 12.10 to 13.04 Ubuntu. The download for 680 MB files were completed successfully. After 10-15 minutes of running, I noticed that the desktop windows got slow,alt tab,switch workspace etc weren't responding. I could open the terminal but no icons to close,minimize and restore. I still let it run for another 6 hours and final with no change I rebooted the system. On reboot it did show Ubuntu 13.04 but all the mentioned problems still persist and it also shows that compiz crashed during installation.
Now how do I run the OS upgrade files again without downloading them. It seem Ubuntu is convinced that the OS upgrade has completed but then I am not sure if it is only the compiz or there are other files also that did not get installed because of this.
So as advised I ran the update-manager-text from terminal but still some errors. Also after running
sudo dkpg --configure -a the above problems still persist.
