Is it possible at all? I've tried alien but I get:
matt@matt-desktop:~$ sudo alien -r '/home/matt/Phython scripts/Guessing game/guessing_game.deb'
[sudo] password for matt:
Control file couldn't be read! at /usr/share/perl5/Alien/Package/Deb.pm line 162.
Nothing useful on google for that whatsoever.
