SOLVED
Hi having problems with KSP v1.12 on Linux Mint 20.1
Can install Ok But will not launch , not even an apparent attempt to launch
I can reinstall V1.11 no problems just not the new one

R5 3600
Gtx 1660ti
48 Gigs

Any hints or help would be great

Thanks in advance

I, too, cannot launch it via the main menu entry in my KDE desktop any more. I can only start it from within CKAN. When I run the start script manually, I get:
/mnt/data/games/ksp ./start.sh
Running Kerbal Space Program
support/gog_com.shlib: Zeile 105: cd: /mnt/data/games/ksp/game/64: No such file or directory
support/gog_com.shlib: Zeile 106: ./ShovelKnight: No such file or directory

It seems as if the start script belongs to Shovel Knight, another game on GOG.

Can you try to reproduce?: Open a terminal in the directory where you installed ksp and enter ./start.sh
What output are you getting?

Thanks felf
I can confirm your findings

had a look at start.sh

will try to edit it and see if it will launch

run_game() {
echo "Running ${GAME_NAME}"
local bin32_name="ShovelKnight"
local bin64_name="ShovelKnight"
local bin_path32="$CURRENT_DIR/game/32"
local bin_path64="$CURRENT_DIR/game/64"
local lib_path32="$CURRENT_DIR/game/32/lib"
local lib_path64="$CURRENT_DIR/game/64/lib"
execute_game "${bin32_name}" "${bin64_name}" "${bin_path32}" "${bin_path64}" "${lib_path32}" "${lib_path64}"
}

The start.sh is messed up use the one for 1.11 it works fine will try to attach it for anyone who needs it until GOG updates the install

Sorry its a jpg small amount of typing required can`t post sh file here


Just clicked that I could copy paste the txt

overwrite the contents of your start.sh with the following code
it worked for me including both DLC`s

Best of Luck and have fun

#!/bin/bash
# GOG.com (www.gog.com)
# Game

# Initialization
CURRENT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
cd "${CURRENT_DIR}"
source support/gog_com.shlib

# Game info
GAME_NAME="$(get_gameinfo 1)"
VERSION="$(get_gameinfo 2)"
VERSION_DEV="$(get_gameinfo 3)"

# Actions
run_game() {
echo "Running ${GAME_NAME}"
cd "${CURRENT_DIR}/game"
chmod +x *
./"KSP.x86_64"

}
default() {
run_game
}

# Options
define_option "-s" "--start" "start ${GAME_NAME}" "run_game" "$@"
