Git issue: Cannot update paths and switch to branch ' Dev ' at the same time.

The following error occurred while creating the remote branch:

$ git checkout-b dev origin/dev

fatal:cannot update paths and switch to branch ' Dev ' at the same time.
Did you intend to checkout ' origin/dev ' which can isn't be resolved as commit?

Internet search a lot of information can not solve, finally to the StackOverflow found the answer: link

Translation: (Do not spray)

As I mentioned in "Get new upstream branch with Git," you can try the following command:

# Let's create a new local branch first
# Let's create a new local branch
git checkout-b iss53
# then reset its starting point# then reset its starting point
git reset--hard origin/iss53 

Make sure that the original trace of the branch origin/iss53 to exist after running the GIT Fetch Origin command.

Origin/iss53 means that the origin index of the remote repository has a ISS53 branch.

If there is no ORIGIN/ISS53 branch in the original repository, you can simply create a local branch iss53 and then push it to the remote repository:

This creates a connection between the local branch iss53 and the branch origin/iss53 of the original trace.
