Pull from one, push to another.
```
git pull othersrc
git log --all
git checkout origin/master
git branch -f master HEAD
git push -u origin master
```
This got this error
```
 ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/johnallsup/pt2_001.git'
hint: Updates were rejected because a pushed branch tip is behind its remote
hint: counterpart. Check out this branch and integrate the remote changes
hint: (e.g. 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
```
So what do we do? Force push.
```
git push -f -u origin master
```
## Set Upstream
```
git branch -u origin master
```
