-----
The spread tests are failing to install lxd 5.9.
The snap channel for lxd 5.9 is now unlisted and can't be directly installed. I filed a bug report https://bugs.launchpad.net/snapstore-server/+bug/2008114
#### Option 1
Follow latest.
```bash
snap install lxd --channel=latest/stable
```
:x: fails
#### Option 2
Pin to another release.
```bash
snap install lxd --channel=5.10/stable # or 5.11/candidate
```
:x: [Error from 5.10/stable](https://github.com/canonical/rockcraft/actions/runs/4245088818/jobs/7380328437).
:x: [Error from 5.11/candidate](https://github.com/canonical/rockcraft/actions/runs/4245574447/jobs/7381414281).
#### Option 3
Workaround to stay on 5.9
```bash
snap install lxd --channel=latest/stable
snap refresh lxd --channel=5.9/stable
```
:heavy_check_mark: succeeds
