======================
Upgrading MediaGoblin
======================
Preparation
-----------
*ALWAYS* take a backup before upgrading, especially before running migrations. That
way if something goes wrong, we can fix things.
Although not strictly necessary, we recommend you shut down your current
MediaGoblin/Celery processes before upgrading.
Upgrade
-------
1. Update to the latest release. In your ``mediagoblin`` directory, run::
git fetch && git checkout -q v0.12.0 && git submodule update
2. Note down any plugins you have installed by reviewing your
``mediagoblin.ini`` configuration. These will be removed by the following
steps and must be re-installed.
3. Remove your existing installation::
make distclean
4. Recreate the virtual environment and install MediaGoblin::
./bootstrap.sh && ./configure && make
5. Re-install any ":doc:`plugins`" you had previously installed. Skipping these
may result in errors updating the database.
6. Update the database::
./bin/gmg dbupdate
7. Restart the Paster and Celery processes. If you followed ":doc:`deploying`",
this may be something like::
sudo systemctl restart mediagoblin-paster.service
sudo systemctl start mediagoblin-celeryd.service
To see the logs for troubleshooting, use something like::
sudo journalctl -u mediagoblin-paster.service -f
sudo journalctl -u mediagoblin-celeryd.service -f
8. View your site and hover your cursor over the "MediaGoblin" link in the
footer to confirm the version number you're running.
Updating your system Python
---------------------------
Upgrading your operating system or installing a new major version of Python may
break MediaGoblin. This typically occurs because Python virtual environment is
referring to a copy of Python that no longer exists. In this situation use the
same process for "Upgrade" above.
