Tested the execution of this workflow here:

• Ubuntu 24.04 spread cjdcordeiro/chisel-releases#11 (with additional mock commits to ensure the logic works when filtering the added and modified files)
• Rocks 1262/add spread tests 24.04 test cjdcordeiro/chisel-releases#13

@rebornplusplus shouldn't other tests have been triggered? there's a change to a slice in this PR...

ah ok! found the reason: https://github.com/canonical/chisel-releases/actions/runs/9908076533

makes sense. I'll "Block" this just so we remember to re-run the tests once we merge the PR for main

Sounds like a plan. Let's do that.

Looks good to me, thank you!

I would wait for the two separate commits - one for the fix and the other for CI.

Just a couple of nitpicks.

Thanks Cris, this is looking good. I see that the CI is failing because it is timing out, I triggered another run to see if it was a transient issue.
