Trying to install Catlateral Damage using the usual extracting and installing commands on the terminal, but it keeps tossing me annoying errors. Probably missing something obvious. Both the archive and the file are on my desktop. Note: the file created by extracting the archive starts out named the same, but then switches to "Linux". I tried renaming it CatlateralDamage too.
