Hi i went to a friends place today and i was unable to upgrade/update or install anything. Here are some of the images of some of the errors i got. I just wanted to install vlc as she is not able to play .3gp files and vlc usually does play them. Then i tried to install other players and encountered the same issue of them not wanting to install. I don't understand the errors as i am still learning but my friend knows far less. sorry i forgot to write down what version of Ubuntu she is using and will not be able to get that info from her as i cant guide her to find out. She only knows how to get on the internet and nothing else.
