Snap package installation fails inside lxd controlled vm

Hi there,
I have a problem installing microk8s snap inside lxd controlled vm.
The error I get is this one

snap install microk8s --classic
error: cannot perform the following tasks:
- Fetch and check assertions for snap "core" (8935) (cannot get device session from store: store server returned status 400 and body "{\"error_list\":[{\"code\":\"invalid-assertion\",\"message\":\"invalid assertion: could not validate model assertion (revision 0 is already the current revision)\"}],\"errors\":[\"invalid assertion: could not validate model assertion (revision 0 is already the current revision)\"],\"result\":\"error\"}\n")

Related lxd topic is here: https://discuss.linuxcontainers.org/t/snap-package-installation-fails-inside-vm/7520

can you please advise?

i think there was an issue with the snap store today that (as i understand) is solved now … try again ?

EDIT: in fact it seems i’m wrong, there still seems to be an issue:

yes, it was an outage. thanks for the tip!
