I am a new ubuntu user, just installed 12.04 LTS. Learned a lot from ubuntu users suggestions on the webs. I am a student and frequent user of MS office.
However, I am unable to install MS Office as failing to get updates plus installing wine1.7.

sudo apt-get update shows something about unable to connect archive.ubuntu.com and some files failed to download, they have been ignored or older ones have been used instead.
sudo apt-get install wine1.7 shows something about unmet dependencies and broken
packages.
