On firewalled machines,
canonical-livepatch needs access to two hostnames:
livepatch.canonical.com, port 443
livepatch-files.canonical.com, port 80
If livepatch client is enabled using ubuntu-advantage, additional access to
contracts.canonical.com on port 443 will be required.
For snap installation, see snap network requirements.
