I installed an upstream openssh using the default-release,
apt install -t testing ... method. Now I wish to downgrade it.
There's a similar question but I believe my question is different because it is specific to the installation/upgrade method I used.
I thought that I could just do it like this:
apt install -V openssh-server -t jessie
but that still picks up the newer repo. There are no preferences or pins set anywhere.
I'm interested in whether there's a way to do this. Please refrain from telling me I've made a FrankenDebian system and I'm terribly stupid for doing so - I've already understood that :-)
