Dear Maintainer,
fastfetch has stopped listing package counts on three sid machines here
and shows zero packages install on three separate sid installations.
If you run fastfetch under the root account the package count displays correctly. I have run apt distclean && apt update which did not resolve
the issue. Permissions inside /var/lib/apt/lists show that all files
allow read access for all users but the auxfiles and partial
subdirectories do not allow read access, which i believe is normal and the directories are empty anyway.
