release-upgrade-motd can't update message

[Hack Saw]

This is a similar bug to the one regarding using a proxy, but I'm NOT using a proxy.

A thing I note: python3-update-manager (Version: 1:18.04.11.9) utils.py url_downloadable doesn't seem to know about https.

url_downloadable: https://changelogs.ubuntu.com/meta-release-lts

If I change the line to """ if scheme == "http" or scheme == "https" """:

Dunno if that's helpful at all, but there it is.

[Brian Murray (brian-murray)]

While you've identified a legitimate bug, the lack of https support, in url_downloadable that function isn't actually used to get the meta-release file. (Wacky I know!) This can be seen by reading UpdateManager/Core/MetaRelease.py's download function.

Please try running do-release-upgrade with the DEBUG_UPDATE_MANAGER environmental variable set e.g. DEBUG_UPDATE_MANAGER=1 do-release-upgrade -c.

Thanks again for your help!

What version of ubuntu-release-upgrader-core do you have installed? This looks like a duplicate of bug 1796940.

And do you have ca-certificates installed?
