I am having trouble getting julia to update on Ubuntu 18.04 running in WSL on Windows 10 version 1709. Pkg.update() takes a few minutes to return the following error. Any ideas would be greatly appreciated.

Maybe it is related to this problem (with solution):

Perhaps, but if that was true, i would expect the Julia install i have on Windows 10 using Windows binaries to also be having update troubles. Its only a problem on WSL, It must be a WSL problem, but i don’t know what the question to ask of the WSL people.
