I'm a bit new to linux (running ubuntu 14.04 - using it about a year), and I've recently started having issues with apt-get.  I can't install or remove any package (error below).  I tried reinstalling these packages, I tried deleting the deb files and I still get the same error.    The following extra packages will be installed:    python3-software-properties software-properties-common    software-properties-gtk    The following packages will be upgraded:    python3-software-properties software-properties-common    software-properties-gtk    3 upgraded, 0 newly installed, 0 to remove and 412 not upgraded.    108 not fully installed or removed.
