Installation Failed On Mint Debian

[asasinuxp]

I've tried to download and install 0ad on Mint Debian,using

sudo add-apt-repository ppa:wfg/0ad
sudo apt-get update
sudo apt-get install 0ad

But at sudo apt-get update I get this error :

N: Ignoring file 'wfg-0ad_dev-debian.list.save' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'wfg-0ad-debian.list.save' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension

How I can fix it?

I think that's just a harmless notice rather than an error, so it should work anyway. I guess those .save files probably exist because you ran add-apt-repository multiple times and it saved backups of the old files - you can clean them up with "sudo rm /etc/apt/sources.list.d/wfg-0ad*.list.save"

Now at sudo apt-get install 0ad:

Reading package lists ... Finished
It builds the dependency tree
Read status information ... Finished
E: Could not locate package 0ad

Mint Debian doesn't handle PPAs. Instead, please download via SVN...
