I recently subscribed to Linux Format, and in the Aug. 2014 issue ('Fix Ubuntu') they recommended apt-fast to install software faster:
$ sudo add-apt-repository ppa:apt-fast/stable
$ sudo apt-get update
$ sudo apt-get install apt-fast
The installation failed, and now I'm getting the red triangle stating my update information is outdated (with two 404 errors related to apt-fast). Also, it says I have no internet connection when trying to switch update servers.
I installed Synaptic to look for the failed install of apt-fast to delete it, but it's not listed anywhere. I also checked /etc/apt/sources.list, but there wasn't any reference to apt-fast that I could find.
So my question is how do I completely delete apt-fast (even if it failed to install), and will that fix the update issue? I'm using Ubuntu 14.04 on an Asus X201E netbook.
Thanks very much.
