Can't update lbw has no tracked branch

It seems like you are encountering an issue with updating a branch that has not been tracked. To update a branch, you need to have it tracked by a remote repository.

To resolve this issue, you can try the following steps:

1. Check the remote branches available:

   git branch -r

2. If the branch you want to update is not listed, you need to set up tracking for it. Track the branch by checking it out and setting the upstream branch:

   git checkout -b <branch-name> origin/<branch-name>

3. Once the branch is tracked, you should be able to update it using the `git pull` command:

   git pull
