Ubuntu 22 and Python 3.10 support?

[aske-cph]

Right now installation fails on Ubuntu 22 and requires Python 2.7?

Question also asked here : https://github.com/nginxinc/nginx-amplify-doc/issues/50 - why is there no questions in here?

Thanks in Advance!

To give a more detailed explenation of the Problem: Ubuntu 22.04 "jammy" comes with Python 3.10.4 installed (as you see HERE) and therefore trying to install the latest package from https://packages.amplify.nginx.com/py3/ubuntu/pool/amplify-agent/n/nginx-amplify-agent/ via dpkg doesn't work

-> % sudo dpkg -i nginx-amplify-agent_1.8.0-2\~focal_amd64.deb

But also if you had the 1.8.0-1 version installed beforehand (which I had) and you try to start it you get

Traceback (most recent call last):

amplify-agent.service: Control process exited, code=exited, status=1/FAILURE

So something has changed in the usage of the psutil package in Python 3.9 or 3.10 I guess... I am not that accustomed to python so no idea how to debug that.

Just ran into this one myself. Kind of seems like amplify is abandonware.

still not working

[thommcgrath]

I noticed that Amplify supposedly supports Ubuntu 22 Jammy according to https://amplify.nginx.com/docs/faq-2-nginx-amplify-agent.html, but... not really? There's no jammy files inside https://packages.amplify.nginx.com/ubuntu/ so install doesn't work.

@thommcgrath if you do have nginx-amplify-agent already installed, you need to adjust your repository URL in order to access newer Python 3 based versions as described here:

https://amplify.nginx.com/docs/guide-installing-and-managing-nginx-amplify-agent.html#updating-the-agent

New installations from official install script (https://github.com/nginxinc/nginx-amplify-agent/blob/master/packages/install.sh) should automatically configure appropriate paths / URLs.
