I've updated 10.04 to 12.04 recently using do release command but now it says minimal graphics problem. Internet is not working due to which I can't download from Internet.
How to update graphics in this case?
restart ubuntu in recovery mode, then automatically opens recovery menu, select repair broken packages, press enter. its a long process, asks permission to continue many time, then press "y " n enter. it will find out the broken file and ask you for update, just press "y", then enter. this worked for me. try all the best
