问题
When I do a git pull, from the git bash, the terminal usually runs the pull, updates my local, and then hangs. I'm not sure if it's waiting for me to do something, but I usually exit out of this with CTRL-C. After that, I get that an index.lock is preventing me from doing other things to which I have to delete it. Am I misunderstanding how git pull works?
回答1:
You may need to remove unnecessary git objects such as dangling commits & blobs:
git fsck && git gc --prune=now
git-fsck : Verifies the connectivity and validity of the objects in the database
git-gc : Cleanup unnecessary files and optimize the local repository
You can refer here about dangling commits & blobs.

I am in Windows, and I solved the hang by closing the Visual Studio before doing the pull.

If you are pulling from a linux machine you may want to check this file:
/etc/ssh/ssh_config
To make sure you aren't setting your default SSH port to something other than 22. Some people get confused between that file and:
/etc/ssh/sshd_config
When they're setting up servers to a non-standard SSH port.
