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. EDIT: 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.

Please do not use do-release-upgrade to upgrade Ubuntu. It tends to break the system. Please use the Update Manager:

  1. Press the super key (Windows key) to open the Dash, type Update Manager.
  2. Hit the Check button then Install Updates, repeat the process until no updates is pending.
  3. Press now the Upgrade button.

    enter image description here

  4. You will be alerted with the releases notes, Hit upgrade again.

  5. Follow the in-screens instructions.

I believe you have problems of dependencies and whatnot, is such cases run sudo apt-get -f install to fix such issues.

Thanks for the reply. Unfortunately the superkey also do not work. –  Ajay Nair Aug 3 '13 at 3:35
    
If you have access to the console you could also type update-manager-text. –  Braiam Aug 3 '13 at 3:37
    
Unfortunately it says it is not installed and when I do a sudo install it says dkpg manager error. It prompts for running sudo configure --a to be run manually. Is that safe –  Ajay Nair Aug 3 '13 at 3:48
    
When the system ask you to run sudo dpkg-configure -a (I believe it's like this) it means that could not configure all the packages on a previous installation, and by all means you can run such command as it's 100% safe, if it fails again, please edit your question and add the new information. –  Braiam Aug 3 '13 at 3:50
    
Perfect. Thank you so much. –  Ajay Nair Aug 3 '13 at 3:53
