First I want to say this I really like Lutrus.
Issue : Installer seems to be using the Linux Steam Client to run the download.
1st install attempt :
Install
-> Which Version -> xlava- port (linux)
-> Set Install Path -> /home/adrian/Games/star-wars-jedi-knight-ii-jedi-outcast
-> Continue
Linux steam client starts so the Download is 0 bytes.
Source does not exist: /home/adrian/.local/share/Steam/SteamApps/common/6030/GamesData
2nd install attempt :
Install > Which Version -> xlava- port (linux) -> Set Install Path -> Continue
Steam client is skipped
Source does not exist: /home/adrian/.local/share/Steam/SteamApps/common/6030/GamesData
“Remove” does not help - retries are the same as 2nd attempt.
Manually deleting the 6030 directory allows the Install to run and again uses the linux.
