Troubleshooting on Linux

Your save folder is ~/.local/share/FasterThanLight/.

Failed to install hook

Fatal Error
Failed to install hook for WeaponControl::RenderAiming:
Failed to make copy of original code executable

SELinux is blocking the Hyperspace library from being linked. Fedora ships with it enabled, so that is where this usually turns up. The fix is to add an exception.

Check whether SELinux is running:
Terminal window
```
sestatus
```
If it is enabled, check whether it is enforcing:
Terminal window
```
getenforce
```
Anything other than Enforcing means SELinux is not your problem.
Build and install the exception. ausearch finds the denial, audit2allow turns it into a rule, and semodule loads it:
Terminal window
```
sudo ausearch -c "FTL.amd64" --raw | audit2allow -M FTLMultiverse && sudo semodule -i FTLMultiverse.pp
```
Swap FTL.amd64 for the executable your architecture runs. If ausearch finds nothing, launch FTL once more to produce a fresh denial and try again.
Confirm the rule loaded:
Terminal window
```
sudo semanage module -l | grep FTLMultiverse
```
You should see something like FTLMultiverse 400 pp.

Launch the game again and it should start normally.

Anything wrong with saves, on Steam

Right-click FTL: Faster Than Light in your library and open Properties.

Right-clicking FTL in the Steam library and choosing Properties

Under General, untick Keep game saves in the Steam Cloud. Turn off Steam Cloud first. It restores outdated saves with broken state, which can keep Hyperspace from launching and will undo any save fix you try later.

Show me the checkbox

The General tab of FTL's Steam properties with the Steam Cloud checkbox unticked

Then under Updates, set automatic updates to Only update this game when I launch it.

Rename FasterThanLight to FasterThanLight-backup, then launch FTL. The game makes a fresh folder, and your original saves stay in the backup if you ever want them back.

Do this once, right after turning Steam Cloud off. Cloud sync leaves behind a save that Hyperspace cannot read, which freezes the game at the end of the loading bar.

My game crashes before loading Multiverse

Make sure you are on the latest Hyperspace. The Multiverse installer is frequently behind, and this is by far the most common cause.

If you are on a laptop with both integrated and dedicated graphics, try forcing FTL onto one or the other. Otherwise your save file is probably corrupt, see below.
