Issues installing gnome system tools in manjaro

normally im able to install gnome-system-tools in gnome manjaro from the AUR and now i get this error below…

“ERROR: Failure while downloading ftp://ftp.gnome.org/pub/GNOME/sources/liboobs/3.0/liboobs-3.0.0.tar.bz2
Aborting…
Failed to build liboobs”

is there a way to install this application or does the package maintainer have to point a new ftp site to install this application??

The liboobs AUR package vas not touched since 2015, but there is a comment there from 2014.

After that build the gnome-system-tools .
