Reference to not working Git URL
https://www.gimp.org/source/howtos/gimp-git-build.html says:
[…] Then, assuming you have all the dependencies, you build GIMP the first time with: git clone git://git.gnome.org/gimp […]
This command yields:
[tim@passepartout /tmp/tmp.Vkd2Egnn0P]$ git clone git://git.gnome.org/gimp
Cloning into 'gimp'...
fatal: unable to connect to git.gnome.org:
git.gnome.org[0: 209.132.180.180]: errno=No route to host
git.gnome.org[1: 209.132.180.168]: errno=No route to host
[tim@passepartout /tmp/tmp.Vkd2Egnn0P]$
The correct URL seems to be https://gitlab.gnome.org/GNOME/gimp.git.
