@posti85 said in Installation fails (due gcc-6 was unable to locate):

Does Raspbian buster (or other debian based dist) may have the same problem?

No, Raspbian includes gcc-6 in Buster (though apparently Debian doesn't). You can also use lr-mgba as GBA emulator.

@vampireJ For a laptop, Ubuntu is recommended as I use that for development (So it's the most tested). 16.04 or better should be fine.

Note, when posting for advice in the future please read https://retropie.org.uk/forum/topic/3/read-this-first (as agreed when registering). Things like hardware platform are important and in this case it would have saved me time.
