Comment 2 for bug 2069292

I haven't seen this timeout before. It's possible it's a transient network/server issue and may be worth retrying in a few hours.

If not, what happens if you launch a lxc container and try to install snapd yourself?

i.e.

lxc launch ubuntu:24.04 u1
lxc exec u1 bash
snap install snapd # or 'snap refresh snapd --channel=latest/beta' to force it to grab something from the snapstore
