Comment 19 for bug 1796193

Strange, that link seems to suggest it is in proposed already, but when I try to run 'do-release-upgrade -p -f DistUpgradeViewNonInteractive', I don't seem to get that. Do I need to do some other manual step to get it first, or do I need it from xenial instead since that's where I'm coming from? Even though I used -p, proposed doesn't seem to be on in /etc/apt/source.list
(after I got the error from above again, I killed the upgrader and checked this)
