repo-add script throws error, fails to add/update packages in local repo

[Daedalusspacegames]

I use paru's LocalRepo and Chroot features to create clean builds of AUR packages. When CachyOS's pacman packages was updated to begin shipping the Rust rewritten version of the repo-add script, this process broke and left me unable to update AUR packages without manual workarounds.

This error does not occur with upstream pacman's repo-add bash script.

that happens, because you don't have files db. which is expected to have in proper environment of local repo

I was able to reproduce when I copy only 'db' and tried to perform action on db (such as repo-remove) -> exactly that happens because it expects 'files' db which doesn't exist.
when copying also 'files' db in the error disappears and it works correctly

You can fix that by recreating db manually once ( to have proper db with 'db' and 'files'):

1. sudo rm /var/lib/repo/aur/aur.*
2. sudo repo-add -s -v -p -n -R /var/lib/repo/aur/aur.db.tar.gz /var/lib/repo/aur/*.pkg.tar.zst

I've tried recreating the db manually per the instructions you gave, and while this served to temporarily solve the problem, upon attempting to update another AUR package via the standard update process the issue has reoccurred.

$ ls -l /var/lib/repo/aur/aur*
lrwxrwxrwx 1 daedalus daedalus      13 Jul 17 08:41 /var/lib/repo/aur/aur.db -> aur.db.tar.gz

As you can see the 'files' db definitely exists.
