I got a warning during the upgrade from 22.04 to 24.04 that deleting systemd-resolved would create name resolution problems (no kidding).
Having completed the upgrade to 24.04, I now have no ability to resolve queries. The obvious solution would be to reinstall systemd-resolved; but apt fails because it cannot resolve 'us.archive.ubuntu.com'. (chicken-->egg-->chicken) I managed to workaround that by adding a temporary entry in /etc/hosts:
91.189.91.83 us.archive.ubuntu.com
But now apt is failing because it can't resolve 'proxy'. Temporary failure resolving 'proxy' I have no proxy configured and there is no host by that name.
What do I need to do to just get systemd-resolved installed?
Or is there new resolver for 24.04 that I need to enable?
Why did do-release-upgrade uninstall it and not replace it?
