When trying to update, use software center, install via apt-get in terminal, open synaptic package manager I get an error that reads "The package mount needs to be reinstalled, but I can't find an archive for it." How can I reinstall the package if none of the instillation apts can mount the file systems to install the broken package?
You don't specify your version, I'll assume you're on 14.04.
There's a package called mount in trusty: http://packages.ubuntu.com/trusty/mount
Try to open a terminal and enter
sudo apt-get update;sudo apt-get install mount.
If all else fails, you can download the package here and install it manually using
dpkg -i mount_2.20.1-5.1ubuntu20_i386.deb.
The dpkg -i thing worked. The only difference was I was on a 64 bit computer so had to use the amd64 package instead of the i386 but I had already found it so that wasn't a problem. Thanks for the quick response. I'll mark this solved. Sep 12, 2014 at 23:21
