* Fix system-snap-refresh in uc20 Simplify the test and validate the base snap during restore is the same revision than the initial one (no need to remove). Also it is included a new function to determine the revision of a snap and the test is updated accordingly. * fix shellcheck * Update tests/core/system-snap-refresh/task.yaml Co-authored-by: Andrew Phelps <136256549+andrewphelpsj@users.noreply.github.com> * Fix spread error in MATCH * make sure not extra output is displayed showing rev --------- Co-authored-by: Andrew Phelps <136256549+andrewphelpsj@users.noreply.github.com>

summary: Check that the ubuntu-core system is rebooted after the core snap is refreshed
|
|
|
|
details: |
|
|
This test checks that when invoking a manual refresh/revert for core or core18 snaps,
|
|
a reboot is triggered and the command would exit after the first phase of the installation
|
|
reporting "snapd is about to reboot the system" or "Change X waiting on external action to be completed"
