Cannot run apt update

[maxnoe]

Trying to install additional packages, running apt update --yes fails with an error (presumably something to do with the new debian release?)
Config:

    docs-folder: docs/
    pre-build-command: apt update --yes && apt install --yes git build-essential pandoc

I'm wondering if skipping the update would help - otherwise they may have to update the base image to bullseye - since as of 19 days ago it's the new stable and buster is the "oldstable" which seems to be what those messages are about.

Update: Yeah, if you skip the update it seems to be working okay. Build link: https://github.com/apache/trafficcontrol/pull/6158/checks?check_run_id=3495291877

So instead of

  with:
    docs-folder: docs/
    pre-build-command: apt update --yes && apt install --yes git build-essential pandoc

just

  with:
    docs-folder: docs/
    pre-build-command: apt install --yes git build-essential pandoc

should work.

Just tried this - this only moves the error down to the apt install stage and we will still lack latexmk for the build (#32).

I think we should update to a newer Debian base image to fix.

Might be specific to latexmk, then, because I'm using it successfully to install pandoc. All that really means, though, is that anything else you install may or may not work and could break at any moment.
