Yesterday my computer ran an update and lost flashplayer. If I try reinstalling it does the same thing which is it can't reach the source or something.

Sorry I'm not computer savvy at all, came to Ubuntu cos I had to and now don't want to leave, so I'm not so good at explaining what's wrong tecnically.

I see others have had a similar problem when updating through a proxy but I'm 99% sure my home network has no proxy's set (my flatmate assures me of this).

I'm on Ubuntu 12.04 I think and use firefox.

The install seems to run fine until it gets to:

flashplugin-installer: downloading http://archive.canonical.com/pool/partner/a/adobe-flashplugin/adobe-flashplugin_11.2.202.297.orig.tar.gz

it then freezes up for a bit and spits a few dummies before coming up with

Failure to download extra data files The following packages requested additional data downloads after package installation, but
the data could not be downloaded or could not be processed.
flashplugin-installer The download will be attempted again later, or
you can try the download again now. Running this command requires an
active Internet connection.

I then try again and it opens a new terminal where it tries to download again from the previous site. Again it just sort of freezes up and after awhile terminal closes but nothing is resolved/flash still doesn't work.

In case it's useful I'll paste my terminal script below, any help would be very appreciated as I don't really want to have to go back to using windows.
