When I try to pull in my project directory in the terminal, I see the following error:
harsukh@harsukh-desktop:~/Sites/branch1$ git pull origin master
U app/config/app.php
U app/config/database.php
U app/routes.php
Pull is not possible because you have unmerged files.
Please, fix them up in the work tree, and then use 'git add/rm <file>'
as appropriate to mark resolution, or use 'git commit -a'.
Why does git say "Pull is not possible because you have unmerged files", and how can I resolve it?
