Update your fork

Keeping your local branch in sync with the upstream is a good practice. In the case of quickstarts we use the develop branch to run ci tests and aggregate changes for release. So it a good idea to keep track of the commit to upstream/develop so you work in progress is easily intregrated.

Updating your fork

Fetch branches from remote.

git fetch --all

    Fetching origin
    Fetching upstream
    .... (updates) ....

The the HEAD of you fork so that it even with your upstream branch

git reset --hard upstream/develop

HEAD is now at a29330a  Commit message of the last commit in upstream/develop

Force push your local changes to your origin. This will upstream/develop and origin/develop even

git push --force-with-lease origin develop

Everything up-to-date
or
Shows pushed changes

Be carefull all the changes in your forks develop branch will be lost. If you have any work in this branch stash it elsewhere!
