How to install Endless Sky 0.9.6 released on Ubuntu

     Endless Sky is a sandbox-style space exploration game similar to Elite, Escape Velocity, or Star Control. You start out as the captain of a tiny space ship and can choose what to do from there. The game includes a major plot line and many minor missions, but you can choose whether you want to play through the plot or strike out on your own as a merchant or bounty hunter or explorer.

Endless Sky Changelog:

• Bug fixes:
• • Coalition jobs will now "repeat" instead of only being offered once.
  • Typo fixes.
  • Fixed a bug that caused wildly inaccurate depreciation values on some computers.

  • Fixed a bug that kept the "Sad Archie" mission from working in 0.9.5.
  • Fixed depreciation not being applied to auto-sold fighters and outfits.

  • Drug running missions now only get offered in human space.

  • Reduced the Unfettered jump drive payoff to be more in line with the drive's depreciated value.
