How to resolve git's “not something we can merge” error

Question

I just encountered a problem when merging a branch into master in git. First, I got the branch name by running git ls-remote. Let\'s call that branch \"branch-n

Answer 1

I had a work tree with master and an another branch checked out in two different work folders.

PS C:\rhipheusADO\Build> git worktree list
C:/rhipheusADO/Build         7d32e6e [vyas-cr-core]
C:/rhipheusADO/Build-master  91d418c [master]

PS C:\rhipheusADO\Build> cd ..\Build-master\

PS C:\rhipheusADO\Build-master> git merge 7d32e6e #Or any other intermediary commits
Updating 91d418c..7d32e6e

If you need to just merge the latest commit:

git merge origin/vyas-cr-core 
git push

And is same as what I've always done:

git checkout master # This is needed if you're not using worktrees
git pull origin vyas-cr-core
git push
