No, they are intended to be the same for split packages. it's pkgname that needs to be unique.
I am aware about the fact the pkgname needed to be unique but I was just double checking that there is no issues with sharing pkgbase's when using the repo-add command, elimination of possible reasons :)
If looking at .PKGINFO doesn't give clues what is wrong, check the changes in the PKGBUILD since the last version that worked.
The thing is, I was the last one to change the code, but it appears the merge of the latest version might have not worked properly, the vcs does not seem to reflect the changes. Will need to investigate before I can comment on this more. -- Polarian GPG signature: 0770E5312238C760 Website: https://polarian.dev JID/XMPP: polarian@polarian.dev
