Hi,
I ran into a problem with one of the VM, it is one I have never experienced and dont know how fix it so any help would be great appreciated. The error is below. I did some research and it could be about proxy but I dont think i’m running behind any proxy (newbie here). I manually run wget and it got the same error. However, running on nearby VM, i can wget it just fine 
Delta RPMs disabled because /usr/bin/applydeltarpm not installed.
