To be honest i got the same result as you did, and after refreshing the search page I got a lot of results, but trying it again just now it failed to find anything , weird.

Odd. Appimage and Flatpak have the same issue. Seems I’ll need to find an alternative.

keescase · November 19, 2025, 2:45pm

Well I don’t use upscayl , so I wouldn’t know , but from the number of results I got (in the end) it is very likely you are not the only one with the problem unfortunately. I only use Irfanview

UncleSpellbinder · November 20, 2025, 6:31am

Odd. No issues with Upscayl in my fresh CachyOS install. Also working on my EndeavourOS install on my laptop.

As far as I can see this is a package from the AUR have you tried removing it from the yay cache and after that clean building it ?

vazicebon · November 20, 2025, 12:17pm

The upscayl-bin package works fine here.
