can,t update xx has no tracked branch

It seems like you are encountering an error message saying "xx has no tracked branch" when trying to update something. This error usually occurs when you try to update a branch that is not being tracked in your local repository.

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

1. Check the list of remote branches available by running the command `git branch -r`. This will show you all the remote branches.

2. If the branch you want to update is not listed in the remote branches, you need to track it first. Use the command `git branch --track <branch-name> origin/<branch-name>` to track the remote branch.

3. Once the branch is tracked, you should be able to update it using the command `git pull origin <branch-name>`.

Remember to replace `<branch-name>` with the actual name of the branch you want to update.

If you're still facing issues, please provide more details about the specific scenario or command you are using so that I can assist you further.
