Git and nasty “error: cannot lock existing info/refs fatal”

Question

After cloning from remote git repository (at bettercodes) I made some changes, commited and tried to push:

git push origin master

Errors

Answer 1

Aside from the many answers already supplied to this question, a simple check on the local repo branches that exist in your machine and those that don't in the remote, will help. In which case you don't use the

git prune

command as many have suggested.

Simply delete the local branch

git branch -d 

as shown in the attached screenshot using -D to force delete when you are sure that a local branch does not have a remote branch tracked.
