So, a while back I installed v1.06 stable using the .deb file, this crashes on startup, I've tried reinstalling and that never worked. In the end I started using the .exe for windows, which works perfectly (apart from the occasional crash). The .deb file installs straight to the opt folder. Since I installed the .deb, I've been unable to update anything, as I get the error meesage "The package xenonauts needs to be reinstalled, but I can't find an archive for it.". I had to force remove it using the terminal. And this has fixed the update problem. But the problem still persists when I try to do a dist-upgrade.
