I am using Ubuntu Server 12.04 LTS, and until yesterday, everything was quite peachy. I have installed several packages (MySQL, apache2) and to my knowledge have those configured correctly. Upon configuration of phpMyAdmin, I found that I was missing the directory path /etc/phpmyadmin, which got me thinking about the install. I am new to Ubuntu, so I guess I missed the message telling me that I did not download phpMyAdmin successfully.
Anyway, trying to use apt-get yesterday/today results in "Failed to fetch..." messages, even if just to run sudo apt-get update.
Some notable details:
···no GUI, command line only (sudo apt-get gksu fails, go figure)
···can ping 4.2.2.2, so I know the internet is out there (somewhere)
···this is a dedicated computer, using Samba to share files with Windows, which does work
···attempted to edit my /sources.list file, for various American/Canadian mirror, to no effect
···ensured I have correct DNS settings in /etc/networks/interfaces
I'm not sure where along the way it happened, but I seem to have lost connections to repositories... :)
Any advice (including GO BACK TO WINDOWS) is appreciated.
