Determining most appropriate PyQt5 package…
…will use PyQt5 packaged by Devuan GNU/Linux 5 (daedalus/ceres).

(Sorry for the swedish part, just says something like “checking package system for previous…”)
Undersöker paketsystemet för att hitta tidigare installerade versioner av Rapid Photo Downloader. Detta kan ta en stund…
Kontrollerar om tidigare versioner installerats med hjälp av pip …

Installing application requirements…

Received error code 1
Failed to install application requirements: exiting.

Well what application requirements are missing?

You might want to try the Debian packages that (should) ship with Devuan, since it’s based on bookworm…
