Sorry, I pasted one of my debugging efforts. The command was due
tracking bullseye-backports, not buster-backport, this is the original
problem:
<code>
root:~# apt -t bullseye-backports search inkscape
E: The value 'bullseye-backports' is invalid for APT::Default-Release
as such a release is not available in the sources
E: The value 'bullseye-backports' is invalid for APT::Default-Release

Question 1: will it work if I remove all /var/lib/apt? I encountered
corrupted vim caches after dist-upgrade so I basically nuke the entire
caches in the user vim directory.
Question 2: For the config files, any specific pattern that we're
looking at? I did clean reinstall against "dpkg" and "apt" packages.
These config files are the current ones and mostly auto-generated and
are using variables. Attached below for each of the files to prevent
