update problem

[Njasa2k]

how do i update the webui? I get this everytime I open the command terminal and type git pull in the webui folder.

`There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.

git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

git branch --set-upstream-to=<remote>/<branch> master`

This command was working in previous updates.
