Error building on Linux: The process '/usr/bin/gpg' failed with exit code 2

Describe the bug

Action randomly (sometimes it works, sometimes it fails) fails by producing this error (+log):

Run swift-actions/setup-swift@v2
  with:
    swift-version: 6.0
gpg: directory '/home/runner/.gnupg' created
gpg: keybox '/home/runner/.gnupg/pubring.kbx' created
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
Error: Unexpected error, unable to continue. Please report at https://github.com/swift-actions/setup-swift/issues
The process '/usr/bin/gpg' failed with exit code 2

Experiencing the same issue, only in our case the action seems to always fail with that same error.

[gmazzo]

Is there any workaround for this?

FYI, I have attached the additional logs.

Is this issue still there for 2.3.0?

[BasinPhoto]

Yes, it is still there

[tomsci]

Assuming swift-actions/setup-swift@v2 will pick up 2.3, yes it seems to be - eg this run from just now: https://github.com/tomsci/LuaSwift/actions/runs/14690274685/job/41224555124?pr=11

[BasinPhoto]

But if you retry to run it several times — it works!

[fwal]

I'm adding a setting for skipping gpg in the 3.0 rewrite, I'll se if I can patch 2.x until then...
