jessie-backports

Someone posted in #devuan a couple hours ago that they ran into trouble with jessie-backports. This is the same problem I had a while ago. If you have jessie-backports enabled in your sources, and you run an update and upgrade, your system will get spammed with backports versions of everything possible. I reported this issue, and someone recently posted a possible fix - https://git.devuan.org/devuan/devuan-pr … #note_8046

Until then, you can prevent this from happening by pinning backports to a lower priority. Put the following into /etc/apt/preferences.d/00backports

Package: *
Pin: release a=jessie-backports
Pin-Priority: 100

This is a lot easier to prevent than it is to fix it. I don't recall exactly what I did to downgrade all the packages I got grom backports, but it may have involved uninstalling a bunch of stuff (including xorg) and then reinstalling. You can see what you have installed from backports with

dpkg -l | grep bpo

I had the same problem with the system being spammed full of backports.

After checking for packages named bpo as above and disabling the backports repository I did the following:

apt-cache show pkgname|grep Vers

From here I just chose the latest version that did not include "bpo" and used apt-get to downgrade the packages individually.

apt-get install pkgname=pkgversion

Where pkgname is the package you want and pkgversion is the latest one returned by the previous command. Where possible I removed and reinstalled packages that wouldn't clobber the system and downgraded the rest. It's a little time consuming, but everything turned out OK.

Thank you very much! Pin priority did the trick, it worked like in wheezy.

Temporarily bump the priority of stable above 1000, it will downgrade
everything to that release.
