Gnome and enabling the AUR

Trying Gnome on a newly acquired HP mini PC. Discovered that despite being enabled in Pamac nothing registers for the AUR. I was going to install drivers for my Brother printer, but the Printer app ended up doing the job.
Whats the score with AUR?

Its up and it works.
We might need more information like … what do you mean exactly?
Just that you search for AUR packages and nothing is returned? Or?..

Enabled in Pamac- database refreshed, . Pamac restarted, searched for ‘Brother’ and nothing came up. Search for anything in AUR and …nothing.
Works ok on a KDE-Plasma install on another PC. And prior to Gnome worked on KDE-Plasma on the this PC. AUR is listed on the left but selecting it comes up blank.
Well guess what, just tried again and there it is!! I’m baffled.

Look here, perhaps:

AUR (en) - Packages

add appropriate keywords

CUPS/Printer-specific problems - ArchWiki

… you didn’t specify the printer model …

There is a known issue with Pamac and AUR metadata and there is known workarounds

Sorry to ‘waffle’ on , but when the AUR did finally appear, entering just ‘Brother’ as a search item ALL Brother entries where listed, I didn’t need to enter the model of printer. My point seems to have been overlooked, there was,despite proper enablement, no sign of ANY AUR entries in Pamac listing.
For my part the problem is sorted, but doesn’t explain why it took so long and several restarts before the AUR just “seemed” to appear out of the Blue.

… one of the reasons why I don’t use pamac
I look in the Arch Wiki (which I linked to) and then on the AUR website …

What @linux-aarhus linked to might count as an explanation - or not.
Who knows? … :man_shrugging:
