Hi i've recently tried to update a Pc but i cannot even get the mouse to work when it boots up. After booting up in safe mode and tried apt-get update etc and got -- you need to dpkg configure -a .But when i tried this it said its a read only file.I Have been warned i'm missing libqt4-xml aswell. This PC is not mine and i'm really in the ____t with it. All i initially wanted to do was update firefox. When i accepted all 491 the United Kingdom server for Ubuntu updates was so slow i pressed cancel and changed it to a Norway Server.After that i got the strange missing libqt-xml file missing and an update manager failer.Can anyone help its an emergancy.
