[Bug] It's impossible to install packages from private Github repos (git+ssh protocol)

My dependencies look like:

"@someorg/somepackage": "git+ssh://[e-mail]:someorg/somepackage.git"

I follow this article to set up my MacOS: https://docs.github.com/en/enterprise/2.15/user/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent

In Yarn 1 it works well.

But in Yarn 2 I see so error:

aleksandr@iMac someproject % yarn
➤ YN0000: ┌ Resolution step
➤ YN0001: │ Error: @someorg/somepackage@git+ssh://[e-mail]:someorg/somepackage.git: Listing the refs for git+ssh://[e-mail]:someorg/somepackage.git failed

I.e. Yarn 1 requests my keychain and uses SSH private key but Yarn 2 doesn’t do it.

@MrEfrem The “git+ssh://” format can still be used in Yarn 2, but others reasons caused this issue.

Thank you so much @arcanis. It’s not a bug of Yarn 2, but I think Yarn 2 may need to help to resolve this problem. While using git+ssh://[e-mail]:someorg/somepackage.git Yarn 2 will run git ls-remote --refs ssh://[e-mail]:someorg/somepackage.git to list remote refs, but git cannot parse the host correctly, it seems to regard github.com:someorg as the host like hostname + port, and will output the error message:

ssh: Could not resolve hostname github.com:someorg: nodename nor servname provided, or not known
fatal: Could not read from remote repository.

Adding a slash after the colon(😃 can resolve this problem:

`git ls-remote --refs ssh://[e-mail]:/someorg/somepackage.git`

So, we need to use git+ssh://[e-mail]:/someorg/somepackage.git instead the old version.

But I think Yarn 2 need to help users to resolve this problem because:

• Both github and gitlab display the incorrect format on there webpages, it’s convenient to copy the URL directly by clicking the copy button.
• Both Yarn 1 and NPM support the format without slash after colon, so, I cannot install some other packages which are using this format in there package.json files.

It turns out, for my yarn it works best, if I run yarn install with the following package.json configuration:

"name": "https://github.com/org/repository"

However, I found this out after running git ls-remote https://github.com/org/repository yielded the refs.
