Error: package installation from azure devops repository

[sivadna]

we maintain internal R package in Azure devops repository, and package installation in R fails with Network is unreachable error.

 library(devtools)
 library(httr)
 set_config(use_proxy(url = 'proxyserver', port = 8080))
 gitcred <- git2r::cred_user_pass('ado user id', 'ado token')
 install_git('ado repository url', credentials = gitcred)

Error: Failed to install 'unknown package' from Git:
Error in 'git2r_remote_ls': failed to connect to dev.azure.com: Network is unreachable

install_git() was working fine until July 2019 and broke since then. Could you guide if there are any devtools function can be used to install packages from Azure devops?

It looks to me like you are missing the protocol, are you passing it to install_git()?

[sivadna]

Yes, below is the sample azure devops url -

install_git('https://[email protected]/TeamName/ProjectName/_git/PackageName',
credentials = gitcred)

I'm doing something similar. I want include an internal package that's hosts on devops as a dependency of another internal package. I can install it from devops with the following, so that the PAT I use for authentication in git is used.

    remotes::install_git(url, git = "external")

I am able to install from a private Azure DevOps repo using remotes version 2.2.0. Note that if you are using a PAT token you can't use credentials = git2r::cred_token() because you need to supply a username.

Authenticate Access with Personal Access Token: Git interaction require a username, which can be anything except the empty string. The PAT is used as the password.

gitcred <- git2r::cred_user_pass('SomeString', 'PAT')
remotes::install_git(
    "https://dev.azure.com/YourOrganization/YourProject/_git/YourRepo",
    credentials = gitcred
)

Authenticate Using External Git Client

remotes::install_git(
    "https://dev.azure.com/YourOrganization/YourProject/_git/YourRepo",
    git = "external"
)

It would be great to have a fully supported version of this for ADO.

remotes::install_git() works inconsistently for packages hosted in ADO. I have one package which installs just fine using the git2r::cred_user_pass() along with the remotes::install_git(). Another one which fails using the same exact code (different repo url hosted in same project) with opaque error

Error : Failed to install 'unknown package' from Git:
  Error in 'git2r_remote_ls'

git2r::remote_ls() succeeds when ran locally. So this is a very difficult problem to debug.

@JosiahParry did you find a solution to your ADO error (Error in 'git2r_remote_ls')?

[JosiahParry]

@mkearney i don't have the code anymore since i'm no longer with the organization. but the code was essentially (pseudo-ish) the below.

What I did was create a temporary directory, clone the repo, install from source, and then delete the temporary directory.

tmp <- tempdir()
git2r::clone("url-of-the-repo", tmp)
install.packages(tmp, repos = NULL
unlink(tmp)
