That's OK - taking a look is already a help. With some assistance from the snapshot.debian.org archives, it seems that these errors began appearing fairly recently: pass: texlive-base (2022.20220605-1) unstable; urgency=low fail: texlive-base (2022.20220923-2) unstable; urgency=medium It should be possible to look at the differences between those (and maybe the related packages such as texlive-latex-base) to find further clues. I'm going to start on that fairly soon.
