I have a bunch of packages "enhanced" by some Debian repository. Now I've disabled that repo from /etc/apt/sources.list.d and I want to re-install all packages that were "enhanced" to... whatever is available. I can get the list of packages just fine using grep, but

apt-get install --reinstall \ $(dpkg-query -Wf '${Version}\t${Package}\n' | grep SOMEREPO | awk '{print $2}' ) 

reports that those packages can't be downloaded. And of course they can't — not at their current version. --reinstall --downgrade is rejected by apt. It seems that the only way to downgrade is to name a specific version (which would require even more nasty scripting for a batch of packages).

Anything I'm overlooking? Maybe aptitude can do it?

Update: I know it can be done via pinning (thanks so much, mods!), but really, that's not a solution. It's laborious, and I don't care about which specific source the downgrade comes from. I want to downgrade to whatever is available from the currently-enabled sources.

Update 2: I'm using a Debian-derivative (MX Linux), so downgrades could come from

• Debian buster
• buster-backports
• the distro-specific https://mirrors.*/mx/MX-Packages/mx/repo/
