Ubuntu 20.10 Pin-Priority does nothing re: apt-cache policy

772

I have several Pin-Priority files set in /etc/apt/preferences.d/ but their settings do not reflect in apt-cache policy

Example:

avery@ChubbyChipmunk:/etc/apt/preferences.d$ ls -la

total 23
drwxr-xr-x 2 root root  7 Oct 22 08:25 .
drwxr-xr-x 7 root root 11 Oct 22 08:13 ..

-rw-r--r-- 1 root root 66 Oct 22 08:25 origin-ppa-launchpad-net-system76-pop-ubuntu

Pinned packages:

I've been able to get Pin-Priority to work before, I have no idea what's going on. I've already spent two hours trying to figure it out, I'm just going to have to comment out the repos in the .list files.

I think I'm going to file a bug report in launchpad.

Any ideas?

Try losing the indentations. I tested with indents and a preference did not take effect. Without any indents, the preference worked. It might also help to have a blank line at the end of each file because that separates the records.

For example

Package: *
Pin: origin apt.pop-os.org
Pin-Priority: 50
