| summary: Ensure auto-install based transition to snapd snap works. | ||
|
|
||
| details: | | ||
| Ensure that we can transition classic systems to snapd snap | ||
| with auto-install of snapd snap from snapd deb or snapd in core | ||
| triggered by any snap install. This change was introduced in PR14173. | ||
| # Exclude Ubuntu Core systems - require proper remodeling | ||
| # Simplify test by limiting system to ubuntu 22.04 amd64 | ||
| systems: [ubuntu-22.04-64] | ||
|
|
||
| environment: | ||
| SNAPD_SRC/deb: "deb" | ||

| prepare: | | ||
| # remove all snaps to remove snapd | ||
| snap remove core | ||
| # this is only possible when snapd is the only installed snap | ||
| snap remove snapd | ||
| # at this point we expect to be running from the deb | ||
| systemctl restart snapd.service | ||
