Hello, walters

This is a fairly minor problem, but the package metadata for gobject-introspection, and gobject-introspection-devel are out-of-date. They currently list the project's URL as

  https://live.gnome.org/GObjectIntrospection

but GNOME no longer uses the "live" subdomain; requests now get redirected to the wiki. I believe the new URL should be

  https://wiki.gnome.org/Projects/GObjectIntrospection

Since you are also listed as the point of contact for other packages, I'll also say that ostree, ostree-devel, and ostree-grub2 have the same problem.

Old URL:
  https://live.gnome.org/OSTree
New URL:
  GNOME Wiki says to go here instead - https://ostree.readthedocs.io/en/latest/

(I'm filing this same bug report for multiple packages, so I apologize if you see this issue twice.)
