Pidgin PPA on Linux Mint Version 10

[Joe H]

Got this when installing the Pidgin PPA on Linux Mint Version 10...

While LinuxMint is supported by the Pidgin PPA, you are running
version 10, which is not.

If this is an old version of LinuxMint, it's probably reached its
end-of-life.  If it's a new version, please use the support at pidgin.im
mailing list to ask for an update to the pidgin-ppa package.
