    Description

      I was playing minecraft for the last few days, started it this morning and everything worked. When I got back from Uni, I got this error (title) when I try to launch the game (after login in, when I press "play") .
      Also tried to install it on another machine, which is also running linux mint, and I had the exact same error:

      [17:50:57 INFO]: Job 'Version & Libraries' finished successfully (took 0:00:00.253)
      [17:50:57 INFO]: Launching game

      If I run the development version (the last snapshot) it works! But I am playing online with my friends therefore I need to be able to play the last stable version.
