Hello All,
I can't get RP-1 to work on Linux Mint 21. (I've also got an unmodded stock install of 1.12.3 which works perfectly.)
For the RP-1 install I followed the latest installation instructions to the letter. Fresh install of KSP 1.12.3 followed by CKAN, Realistic Progression One (RP-1) Express Install and all the automatically recommended extra mods.
The game starts OK, although I get a message "Missing RSS Texture Pack" during loading (RSS-Textures folder is present and correct in GameData). I can choose New Game and get as far as the Space Centre screen. All the toolbar buttons work but the pause menu won't allow me to save or exit the game. I can't enter any buildings except the Astronaut Complex and the exit button doesn't work there so I can't get back out of it. All I can do is Alt-Tab out of the game and close it from the desktop.
One oddity I noticed is that there's an orphaned GameData folder in my Home folder which contains a few different files to the proper GameData folder in the KSP installation. It was added sometime during the installation process by CKAN. I tried copying the additional files into the game but that didn't make any difference.
I've searched for posts about this problem but couldn't find anything.
Any ideas?
Thanks
