summary: Verify snap debug execution command
details: |
This test checks that the command `snap debug execution` shows right
outputs, but also verifies their correctness on the target systems
skip:
- reason: Snapd is from the archive and `debug execution`command could not be supported
if: |
# TODO: remove this check once snapd 2.65 is released (debian-12 missing)
tests.info is-snapd-from-archive
debug: |
grep -n '' snap-*.out || true
execute: |
