Nightly Subsurface AppImage for most Linux distributions

[Dirk Hohndel]

So I had a little time to play with this and am running into issues... I'm
sure it's just the difference in setup or something...

What did I do?

- installed Ubuntu 12.04 in a chroot (to make sure I have an at least 3yo
  build environment
- chrooted into that and tried to run the subsurface.sh

Here's the output:

Reading package lists... Done

Package p7zip-full is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only
available from another source

it continues from here (maybe it should stop when it runs into errors).

I'll poke around a bit to see if I can make sense of what's happening, but
figure I should let you know :-)
