Now that "snapd" snap is seeded into the base image of focal along with
core18 for "lxd" snap . That actually solves the original issue in a
different way. We no longer have to upload "snapd" snap using a charm
resource.
Bionic is still affected, but I don't think it's common for new
deployments
** Summary changed:
- snap installation with core18 fails at 'Ensure prerequisites for "etcd" are
available' in air-gapped environments as snapd always requires core(16)
+ snap installation with core18 fails at 'Ensure prerequisites for "etcd" are
available' in air-gapped environments as snapd
