Checkout branch on different remote

问题:

I have a repo that has another remote upstream besides origin. I can do git checkout origin/master, but when I run git checkout upstream/master, I get:

error: pathspec 'upstream/master' did not match any file(s) known to git.

This does not work either:

$ git fetch upstream
From https://github.com/getsentry/sentry
 * branch            HEAD       -> FETCH_HEAD
$ git co -b asdf --track upstream/master
fatal: Cannot update paths and switch to branch 'asdf' at the same time.
Did you intend to checkout 'upstream/master' which can not be resolved as commit?

How to check out branches on upstream remote as I do on origin remote? My git version is 2.1.2.

回答1:

Just fetch the refs from the remote (this will fetch all branch, commit, refs etc for the upstream repo)

git fetch upstream

After this, checkout the needed branch (this creates a local copy of the branch)

git checkout -b <branchname> --track upstream/<branchname>

Now if you want to pull the changes in this branch in future, all you need to do is

git pull upstream <branchname>

---

As mentioned here, try doing an explicit fetch on the branch name:

git fetch upstream master:branch_name

回答2:

If you just added the remote, you'll need to fetch it so that Git knows which branches are available:

git fetch upstream master

After this you can do

git checkout upstream/master

without any issues.
