More problems trying to add packages from private repos

[CameronBieganek]

There have been many threads about the difficulties of using private repositories with Pkg. Here’s one, which contains links to various other threads:

Basic introduction to ssh-agent, libGit2 in the context of Pkg

This thread (and this, and this, and this) discuss a situation where something called “ssh-agent” is involved in preventing Pkg.add() from repeatedly requesting to override the private key location (when the existing one is actually valid), and ultimately failing: julia> Pkg.add(url="git@github.com:me/myrepo.jl.git") Cloning git-repo `git@github.com:me/myrepo.jl.git` Private key location for 'git@github.com' [/home/me/.ssh/id_rsa]: Private key location for 'git@github.com' [/home/me/.ssh/i…

At some point in the past I managed to get things working somehow, but now they appear to be broken again and I don’t know how to fix it. I decided to throw in the towel and connect to one of my private repos with HTTPS instead of SSH. And yet I still can’t actually add the repo. Here’s what happens:

(PackageA) pkg> add https://github.com/CameronBieganek/PackageB.jl.git
    Updating git-repo `https://github.com/CameronBieganek/PackageB.jl.git`
Username for 'https://github.com': myemail@gmail.com
Password for 'https://myemail@gmail.com@github.com': 
Username for 'https://github.com' [myemail@gmail.com]: myemail@gmail.com
Password for 'https://myemail@gmail.com@github.com': 
Username for 'https://github.com' [myemail@gmail.com]: myemail@gmail.com
Password for 'https://myemail@gmail.com@github.com': 
ERROR: failed to fetch from https://github.com/CameronBieganek/PackageB.jl.git, error: GitError(Code:EUSER, Class:Callback, Aborting, user cancelled credential request.)

What am I doing wrong? Why is this so hard? For now I’m giving up and and making one of my private repos public.

Mandatory question: can you git clone the package outside of Julia?

If that works you may want to try the Julia 1.7 release candidate with JULIA_PKG_USE_CLI_GIT=true, see julia/NEWS.md at release-1.7 · JuliaLang/julia · GitHub.

I don’t know why connecting with HTTPS doesn’t work, but some time ago I also experienced issues adding my private packages via SSH. I think my problem was I was generating an SSH key that was incompatible with LibGit2. Once I generated a compatible SSH key things worked seamlessly. (See LocalRegistry.jl/ssh_keys.md at master · GunnarFarneback/LocalRegistry.jl · GitHub for details.)

Thanks for the responses. Generating a new SSH key with the -m PEM option seemed to do the trick. Maybe when 1.7 is officially released I’ll use the JULIA_PKG_USE_CLI_GIT=true option.
