Public bug reported: I use mirror://mirrors.ubuntu.com/mirrors.txt as Ubuntu package repository on my laptop, since I used to (thanks to COVID) travel and wanted to use fastest mirror whenever possible. It works great, however do-release-upgrade/update-manager both fail with those: they report as if ubuntu-minimal package is missing (and I've checked that isn't the case in all mirrors chosen by mirror://). So for last 3 updates or so I have to manually switch mirror:// repository to some regional http:// one, then update-manager does it's thing, then I switch back and everything works as expected.
I think that behaviour of do-release-upgrade can be fixed.
