Can't push the fixed bug in "save your work"

[abalter]

I did the following:

1. stash
2. fix bug
3. add and commit
   I get an error when I try to push.

What am I missing?

working area is a total mess so you don't feel comfortable with making a commit now. However, you need to fix the found
bug ASAP.

Git lets you to save your work *on a side* and continue it later. Find appropriate Git tool and use it to handle
the situation appropriately.

Look for a bug to remove in `bug.txt`.

After you commit the bugfix, get back to your work. Finish it by adding a new line to `bug.txt` with

    Finally, finished it!

Then, commit your work after bugfix.
