When flatpak is not installed, Scummvm games from GoG cannot launch

[Kingwad]

Describe the bug

Running heroic natively installed, not using flatpak. Flatpak is not installed on the system. Running Scummvm games from GoG attempts to load flatpak version of scummvm and fails to fallback to alternate versions.

Steps to reproduce

• Without flatpak installed on system:
• install native version of scummvm
• Install GoG scummvm game via Heroic (eg. Space Quest 4)
• Attempt to run game
• remove native version of scummvm
• Attempt to run game

Expected behavior

Heroic should not abort the search for an appropriate scummvm if flatpak is not installed. It should fail to launch the flatpak version, then attempt the other options in the expected order "flatpak scummvm, in path scummvm, wine scummvm"

A temporary workaround is to put a symbolic link to false called flatpak in the path. Then it will find the fake flatpak, which will error out, and successfully fallback to the scummvm in path or the wine version as expected.

On inspecting the code, this issue should probably be moved to https://github.com/Heroic-Games-Launcher/heroic-gogdl, as the error is there.

https://github.com/Heroic-Games-Launcher/heroic-gogdl/blob/1ff09820915f855ea764c6e49ea2def63e86b3bb/gogdl/launch.py#L96

https://github.com/Heroic-Games-Launcher/heroic-gogdl/blob/1ff09820915f855ea764c6e49ea2def63e86b3bb/gogdl/launch.py#L106

Either catch the FileNotFoundError exception thrown by get_flatpak_command in both of these locations or don't throw the exception at all.

this was solved in gogdl 1.1.2 https://github.com/Heroic-Games-Launcher/heroic-gogdl/releases/tag/v1.1.2

you can use that binary as an alternative binary in heroic temporarily until the next release (in settings > advanced)

[Kingwad]

Thank you, I can confirm that heroic-gogdl 1.1.2 indeed works as expected

[arielj]

closing since gogdl 1.1.2 was included in heroic 2.15.2
