I have forked Mautic on github, then cloned the repository locally onto my Win10 box.
Now I want to pull some PRs into my repository for testing. John pointed me to https://github.com/mautic/mautic#how-to-test-a-pull-request but I am stuck. This is what I get:
$ git checkout staging
Switched to branch ‘staging’
Your branch is up-to-date with ‘origin/staging’.
$ git fetch origin pull/4674/head:staging
fatal: Couldn’t find remote ref pull/4674/head
How do I get a PR into my own repository? I hope I don't need to clone mautic/mautic or escopecz/mautic for this, do I ?
