`remotes::install_git()` fails when {git2r} is installed

[lschneiderbauer]

When trying to install a package from our internal gitlab instance while {git2r} is installed,

remotes::install_git("git@gitlab.xxx:yyy.git")

I am getting

Fehler: Failed to install 'yyy' from Git:
Error in 'git2r_remote_ls': unsupported URL protocol

("xxx" and "yyy" is a placeholder for redacted information)

Now, when removing the git2r package, and issuing the same command again, the command works as expected and installs the package.

How can the presence of {git2r} influence the outcome of remotes::install_git() ?

Same here. I'm developing a package with a private DevOps dependency, which itself has another DevOps dependency.
On devtools::install() I'm getting:

Error in 'git2r_remote_ls': no error

Removing git2r solves the issue.

Consider adding a backup system in case the git2r method fails, or use it exclusively if base Git is not available while git2R is, instead of defaulting to git2r.

I’d like to work on reproducing/fixing this — I’ll open a PR when ready.
