[ubuntu] Foobnix!

Ubuntu 16.04 LTS
I installed it in Romanian and the terminal input is also in Romanian
sudo apt-get install foobnix
Citire liste de pachete... Terminat
Se construiește arborele de dependență
Se citesc informațiile de stare... Terminat
Pachetul foobnix nu este disponibil, dar este menționat de către alt pachet.
Aceasta ar putea însemna că pachetul lipsește, s-a învechit, sau
este disponibil numai din altă sursă

Which translates as the foobnix package is unavailable, but is mentioned by another package. This could mean that the package is missing, is outdated, or is only available from another source.

Also, from the previous terminal command:

W: The repository 'http://ppa.launchpad.net/foobnix-team/foobnix-player/ubuntu xenial Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/foobnix-tea...amd64/Packages 404 Not Found
