Comment 2 for bug 1895385

Re-assigned to snapd as the error was:

```
error: cannot install "lxd": Post https://api.snapcraft.io/v2/snaps/refresh: dial tcp: lookup
       api.snapcraft.io: device or resource busy
```

And this was after passing the store connectivity check (snap info).

`device or resource busy` is a rather weird one for a connection failure, so I'm not sure what that's about and maybe snapd ought to attempt a retry on such failure?

In any case, I would expect re-trying the upgrade to succeed, assuming this was indeed a transient error coming from store communication.
