I've had a similar symptom... plus a couple other problems today:

Today, when I ran "yum update", there were about 700 or 800 packages 
which tried to update.  Only about 20 successfully installed, all the 
others failed due to dependency problems.  But I found that if I picked 
just one or three or a half dozen packages out from the huge list of 
failures, they would update successfully, including the dependencies 
they required.  Doing this repeatedly, I successfully updated most of 
those 800-some packages.  Only 16 still wouldn't install due to 
dependency issues, the same packages as listed above, i.e.:

Packages skipped because of dependency problems:
     gvfs-1.30.4-3.el7.x86_64 from base
     gvfs-afc-1.30.4-3.el7.x86_64 from base
     gvfs-afp-1.30.4-3.el7.x86_64 from base
     gvfs-archive-1.30.4-3.el7.x86_64 from base
     gvfs-client-1.30.4-3.el7.x86_64 from base
     gvfs-fuse-1.30.4-3.el7.x86_64 from base
     gvfs-goa-1.30.4-3.el7.x86_64 from base
     gvfs-gphoto2-1.30.4-3.el7.x86_64 from base
     gvfs-mtp-1.30.4-3.el7.x86_64 from base
     gvfs-smb-1.30.4-3.el7.x86_64 from base
     libimobiledevice-1.2.0-1.el7.x86_64 from base
     libplist-1.12-3.el7.x86_64 from base
     libusbmuxd-1.0.10-5.el7.x86_64 from base
     upower-0.99.4-2.el7.x86_64 from base
     usbmuxd-1.1.0-1.el7.x86_64 from base

In addition, subsequent to this (mostly successful) update, the sound no 
longer functions.  Even audacity and vlc produce no sound, and they have 
always worked, even when all other sound apps on this system didn't.

It's perhaps worth noting that I don't have mate installed and have had 
no network problems since this major, partially horked update.

At this initial stage I'm suspecting a problem with yum or rpm (both of 
which were in the huge list of updated packages).  For instance, vim was 
one of the many packages which failed due to "dependency" issues.. until 
I updated it separately, by itself.

Does this lead anyone to suggest a solution, or a next step?
