Upgrade killing the image?

[magudelo58]

Hello,

I downloaded the latest version from http://www.alarmdecoder.com/downloads/p ... -05-22.zip and flashed in the SD card of my Raspberry PI.

Everything was working without problem until I applied updates and upgrades to the OS using apt-get.

After the upgrade NGINX was removed from the packages, (I have not clue why this happened), so I had to reinstall it.

After the reinstall, I tried bouncing the services (nginx and gurnicon) and noticed the server was reporting: "Services might still be starting - please wait and try again. If this continues, please let us know on GitHub. You can also email us at Support."

This is the log from /var/log/gunicorn/alarmdecoder.log

I also tried initializing the database, but no much luck here.

So the question is: why updating/upgrading the OS is cauing so many issues?

We use and compile from source a specific version of nginx with our image. It is detailed in our instructions. It is specifically for websocket support.

This was posted in the wrong section, so I am going to move it.

gunicorn version 19.3.0 and nginx version 1.7.4 are required for this. If you are doing an update you will need to hold these packages back from the update, you can do this with an apt-mark hold on the packages:

sudo apt-mark hold gunicorn for example

or

sudo echo "gunicorn hold" | sudo dpkg --set-selections

After looking at this more closely, it seems that the pip version might be to blame for the build_prefix import error seen. If you can revert the pip version, it should work until we push out a fix to support the new pip version(s) in the requirements updater.

Advice on gunicorn and nginx still stands!

Until we figure out what the newest pip changed/broke and handle it in the code accordingly, I suggest using the same pip version provided by our image - version 6.1.1
