So I downloaded Ubuntu 12.10 on a Dell mini Inspiron 910. Had problems with wifi, but I bought a wireless adapter and so I fixed that. But when I try installing flash, with sudo apt-get install flashplugin-installer gsfonts-x11
it gives me:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package gsfonts-x11 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
E: Unable to locate package flashplugin-installer
E: Package 'gsfonts-x11' has no installation candidate
which I don't really understand.
