I set up VirtualBox and installed todays daily mate iso using zsync.
/media/pfeiffep/ExtData/VirtualBox/MATE$ zsync http://cdimage.ubuntu.com/ubuntu-mate/daily-live/current/yakkety-desktop-amd64.iso.zsync
1 error on install then 1 error on update. I didn't see the install error in syslog
I changed the source to main form US with same results
