received this error when git merge in terminal did not finish and now there seems to be a lock that won't let me push/do merge because of this error.
fatal: cannot lock ref 'HEAD': Unable to create 'C:/Users//.git/HEAD.lock': File exists.
Another git process seems to be running in this repository, e.g.
an editor opened by 'git commit'. Please make sure all processes
are terminated then try again. If it still fails, a git process
may have crashed in this repository earlier:
remove the file manually to continue.
What do you suggest?
