Unable to reproduce using latest/stable (3.8)

Is this reproduceable if you "snapcraft clean --use-lxd && snapcraft --use-lxd"?

[Adam Collard (adam-collard)]

Seems not

[Sergio Schvezov (sergiusens)]

Thanks for confirming. For other people looking at this bug, marking the issue as Invalid was due to avoiding the problem but a solution is still warranted and that is to avoid using the "snapd" snap if "core" is already in place for existing systems.

The workaround today is to clean and start fresh.

Something I've seen a lot of switching between 3.8 and 3.9.x. I assume this may be related and worth noting here:

Running `snapcraft clean` does fix it.
