The problem is in the updater not handling the url

Good thing 'he development and maintainership of Megapixels has been moved to' then :-)

Could you update the URL and try again? If you want you can report and/or investigate Guix's apparent failure to deal with separately.

+       (file-name (string-append name "-" version ".tar.gz"))
Use git-file-name here for convenience and to reduce the chances of such paste-os.

+    (native-inputs `(("pkg-config" ,pkg-config)
+                     ("gtk:bin"
+                      ,gtk "bin")       ; for gtk-update-icon-cache
+                     ("glib:bin"
+                      ,glib "bin")      ; glib-compile-schemas, etc.
+                     ("desktop-file-utils"
+ ,desktop-file-utils) ; for update-desktop-database
+                     ("zbar" ,zbar)
+                     ("libtiff" ,libtiff)
+                     ("cmake" ,cmake)))

Please add a newline after native-inputs so you don't have to split inputs over 2 lines like this. Since we're here anyway, order these alphabetically.

+    (inputs `(("libhandy" ,libhandy)
+              ("perl-image-exiftool" ,perl-image-exiftool)
+              ("imagemagick" ,imagemagick)
+              ("libraw" ,libraw)
+              ("gtk" ,gtk)))

Same newline.

+    (synopsis "Camera application")

So... ignoring the redundant 'application', this is a one-word synopsis. This seems to be for mobile devices, so 'Camera applications for mobile devices', I guess.

+    (description "This package provides camera application that knows
+how to deal with the media request api.")

Whose obscure 'media request API'?  Why does that matter?  Etc.

This seems (more?) pertinent:

- Megapixels only captures raw frames and stores .dng files.
- It captures a 5 frame burst and saves it to a temporary location.
- It runs a (customisable? dunno) postprocessing script to generate the final JPEG file and saves it to the Pictures directory.
- It uses OpenGL to debayer the raw sensor data for the preview.

Etc.  Descriptions should not be 1-2 lines long.

+    (home-page "";)

Also update to GitLab?

I'll build this later today, but I don't expect to find any issues with the package :-)

Kind regards,
