Estoy probando y tiene buena pinta.

Don't Panic
Version: 2.0

"Dontpanic is a free (as in 'freedom') python application to look for any movie or serie and watch them in 'streaming'. It looks like Popcorn Time or Torrents Time, but doesn't depend of a centralized api. ☺

This has been made by two independent developers who love free software! ♥"

Lo encontré en repositorios AUR.
No sé como será en otras distribuciones.
