Additional Information

The same issue has already been submitted here: https://github.com/portainer/portainer/issues/8732 but couldn't be reproduced because not a self hosted Azure DevOps was used for testing.

The underlying issue seems to be that go-git didn't support multi_ack and has been discussed here: https://github.com/portainer/portainer/issues/1926 which resulted in a workaround that downloads the repository as a zip-file instead of using git clone. If I understand the code correctly it just checks the domain part of the URL to detect if it is an Azure DevOps repository or not:

https://github.com/portainer/portainer/blob/develop/api/git/azure.go

const (
    azureDevOpsHost        = "dev.azure.com"
    visualStudioHostSuffix = ".visualstudio.com"
)

func isAzureUrl(s string) bool {
    return strings.Contains(s, azureDevOpsHost) ||
        strings.Contains(s, visualStudioHostSuffix)
}

While this works fine for the cloud version it fails to detect self hosted Azure DevOps repositories and tries to use git clone instead.

Now an easy fix would probably be something like a "Is Azure DevOps repository" checkbox in the Add Stack GUI to force the zip download instead of git clone or an additional setting to add custom Azure DevOps domains. It also seems that the underlying issue in go-git has been partially fixed by now: https://github.com/go-git/go-git/issues/64 so maybe that would also be an option.

Is there any fix for this? I can not use our internal devops environment with portainer.
