i'm using UBUNTU 12.04.. i like to install FIREFOX BROWSER... but not
installed.. it shows "FAILED TO DOWNLOAD PACKAGE FILES".. i'm downloading it
form "UBUNTU SOFTWARE CENTER"... help me>>>>
I have read similar threads. <sudo apt-get update> returns many 404 errors and few updates. <sudo apt-get install firefox> returns, "Package firefox is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source".
