Over the last few days you have not been able to update arch (and antergos)due to an error in a libsoup dependency. IT points to gstreamer 0.10, which was depreciated in Arch.

From the Arch developers mail archive

Actually a new release is out 3.1.0 with gstreamer 1.0 support. [1]

There is a bugreport for compilation with wxgtk, maybe it's applicable
for other packages depending on wxgtk2.8 although most of them have
better alternatives... [2]

veracrypt replaces this package I'd say.

This is required by at least 2 other packages: 
    - cycle (dead upstream) , mayavi (as dead upstream ~ 2005)

P.S.

seems new years clean up has started :)

Mayhbe I should drop pygoocanvas and goocanvas1 too.

The simplest way to fix this is graphically. Open up pamac and deselect all of gstreamer 0.10

Remove these, then close pamac. Then update, either from the command line or graphically. Gnome has been updated, which means that Cinnamon also has a large update. I have done this on three machines with good results.
