Ghostty snap in Fedora 41 does not run with /snap/bin/ghostty

[kenvandine]

Discussed in #6606

^{Originally posted by SuperMatt March 6, 2025}
Since installing ghostty snap revision 32, the snap no longer loads.

If I run /snap/bin/ghostty or snap run ghostty from the command line it returns immediately with exit code 1.

Running /snap/ghostty/32/bin/ghostty does load ghostty correctly.

Running snap run --debug-log ghostty under revision 21, which is the previous revision that does work, this is the output (until I close ghostty):

$ snap run --debug-log ghostty

Running the same as revision 32 gives the following output:

I have tested revision 32 in Ubuntu 24.10 and it does work, so this is a problem limited only to Fedora (or at least the tested version, Fedora 41).

Tagging @kenvandine as the current maintainer of this snap.
