Comment 18 for bug 1710022

We currently get the below on an IPv6 only host. Looks like snapstore.io is a legacy system, is it going away?

Connection to the Snap Store failed

You have the package lxd installed but your system is unable to reach
the Snap Store. lxd is now provided via a snap and the release
upgrade will fail if snapd is not functional. Please make sure you're
connected to the Internet and update any firewall or proxy settings
as needed so that you can reach api.snapcraft.io. If you are an
enterprise with a firewall setup you may want to configure a Snap
Store proxy.
