Julia crashes when adding package with ssh, https works

General Usage

1

Trying to add a unregistered package from my github account using ssh causes Julia to crash.

I replaced my boot drive in my windows PC and I am in the process reinstalling everything. I have set up a new private/public key pair with git/github. It’s been several years since I have added a package with shh, but it did work in the past.

Any sugestions?

I did some more troubleshooting. Github ssh connection works in the mingw64 shell, but not in shell mode from Julia. This problem may not be with Julia, but if someone on this forum could point me in the right direction it would be great.

In MINGW64:

chris@DESKTOP-TJIALUM MINGW64 ~
$ ssh -T git@github.com
Hi cstook! You've successfully authenticated, but GitHub does not provide shell access.

In Julia shell:

shell> ssh -T git@github.com
git@github.com: Permission denied (publickey).

The Julia window is no longer working at this point.

This kills my command line too.

This looks OK, but the shell has crashed and Julia needs to be restarted.

The verbose test throws a bunch of errors, successfully authenticates, then crashes.

Are other Windows users able to connect to github via ssh in julia shell mode?

The original libssh2 crash occurs to some of my colleagues as well, possibly starting after some relatively large Windows update.
