### Electron Forge version

6.2.1

### Electron version

25.0.1

### Operating system

Q4OS (Debian based)

### Last known working Electron Forge version

_No response_

### Expected behavior

When I run **npm run make** (the command to make the executables), I should get both .deb and .rpm executables.

### Actual behavior

When I run **npm run make**, I correctly get the .deb file, but the .rpm build report the following error:

An unhandled rejection has occurred inside Forge:
Error: Command failed with a non-zero return code (1):

### Steps to reproduce

I guess the starter project, and a Linux machine, would be fine to reproduce this.
