You sure know this problem: You run a stable Ubuntu version and the package you want is slightly older than the one advertised on the project’s site. So what, you install it via apt-get and that’s it. Well sometimes, that might not be the best idea.

The Ubuntu uWSGI package is on version 1.0.3. So when I had some tough problems last week I thought it was best to update from the Ubuntu version to the latest version 1.9.14. Here’s how:

Thankfully, uWSGI can be installed via PIP:

sudo pip install uwsgi

1

sudo pip install uwsgi

It installs in /usr/local/bin/uwsgi, but the version you probably have uses /usr/bin/uwsgi. No problem, just redo the symlink to the newer uwsig:

sudo ln -fs /usr/local/bin/uwsgi /usr/bin/uwsgi

1

sudo ln -fs /usr/local/bin/uwsgi /usr/bin/uwsgi

One more thing: Because the PIP version of uWSGI has python already included, remove any plugins=python lines from your uWSGI config files.

That should be it. Stop all uwsgi processes (check ps aux to see they are really gone) and start again with service uwsgi start. Your system now uses the new uWSGI version while having the uWSGI setup that came with the Ubuntu package.
