[aur-general] mate-common-dev missing Source File

[Dan Sommers]

Greetings,

I tried to install mate-common-dev¹ this morning, but it fails to
download its source file²:

   -> Downloading mate-common-1.21.0.tar.xz...
   [... curl progress meter skipped ...]
curl: (22) The requested URL returned error: 404 Not Found
==> ERROR: Failure while downloading 
http://pub.mate-desktop.or/releases/1.21/mate-common-1.21.0.tar.xz
     Aborting...

I checked the source directory,³ and sure enough, there is no
mate-common tarball there.

A lot of other mate-*-dev packages depend on mate-common-dev; what's the
easiest path forward to a mate-desktop-dev installation?

Thanks,
Dan
