Plugin Install Fetch Failed

Just installed a fresh copy of Learn2 with Git Sync Site skeleton, then performed an update of the site. Next, I tried to install some plugins and I get an error on many but not all plugin installations …

“Fetch Failed:
undefined is not an object (evaluating ‘f.Instance.payload.payload.resources’)

Suggestions?

Hi @Umbergerba, is this the case with other skeletons too? Have you re-tried the install recently?

When I was going to install itunes on windows 7 it was literally crashing and I could not install it at all so please help me to fix the problem so that I can work with it.
