Pkg.update() fails

[Phillip_Gurman]

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):

Errors for Git / Pkg

There have been various reports of issues running package operations recently. They manifest as one of the following messages on running any package operations, such as Pkg.init or Pkg.add: ERROR: GitError(Code:ERROR, Class:Net, SSL error: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version) or ERROR: GitError(Code:ECERTIFICATE, Class:OS, user cancelled certificate check: ) This is happening because GitHub stopped supporting TLS 1.0 in February: The error occu…

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.
