Re: A number of problems after upgarde of Ubuntu from 18.04->20.04

ok, Ubuntu 20.04 removes uwsgi plugin for Python 2 support. You have to install "uwsgi" with "pip2" command instead:

pip2 install uwsgi

It installs /usr/local/bin/uwsgi (the "uwsgi-*" deb packages install /usr/bin/uwsgi), so you need to replace "/usr/bin/uwsgi" by "/usr/local/bin/uwsgi" in /etc/systemd/system/multi-user.target.wants/iredadmin.service.

You may need to remove the "plugins =" line in /opt/www/iredadmin/rc_scripts/uwsgi/debian.ini also.

Requirement already satisfied: uwsgi in ./.local/lib/python2.7/site-packages (2.0.18)

So uwsgi was already installed so I changed the /etc/systemd/system/multi-user.target.wants/iredadmin.service to below and rebooted the server afterwards

uwsgi is running Python 3.8.2 for your iRedAdmin, this is not right.

Please make sure you're using a uwsgi program built for Python 2.

Re: A number of problems after upgarde of Ubuntu from 18.04->20.04

What's the "plugins =" line in /opt/www/iredadmin/rc_scripts/uwsgi/debian.ini ?
It should contains "python2", not "python3" or "python36", "python38".

As per your earlier advice, the plugins line was removed. With

plugins = python2,syslog

it looks like below

As you can see, /usr/local/bin/uwsgi is built with Python 3.8, not Python 2.

Which uwsgi program is specified in /etc/systemd/system/multi-user.target.wants/iredadmin.service? Please make sure it's the one built with Python 2 or has Python 2 support.

Re: A number of problems after upgarde of Ubuntu from 18.04->20.04

I'm confused why it didn't work on your server.

Ubuntu 20.04 doesn't ship uwsgi-plugin-python anymore, so we have to install uwsgi with Python 2.

wget https://bootstrap.pypa.io/get-pip.py
python2 get-pip.py
pip2 install uwsgi web.py==0.51 pymysql
service iredadmin restart

I now managed to make the python27 plugin from the uwsgi source but that led me to not being able to import web again even though the web-py package is installed

Re: A number of problems after upgarde of Ubuntu from 18.04->20.04

Hmm, we're looping back.

Try one more time:

- Install uwsgi: "pip2 install uwsgi". It should install /usr/local/bin/uwsgi.
- Update  /etc/systemd/system/multi-user.target.wants/iredadmin.service, replace /usr/bin/uwsgi by /usr/local/bin/uwsgi.
- Update /opt/www/iredadmin/rc_scripts/uwsgi/debian.ini, remove the "plugin" line.

Now restart "iredadmin" service and check /var/log/syslog, also try to access it from web browser.

I can do that later, but uwsgi is not the problem anymore. Now it is the import web that's next. This is the same problem I had with IredAPD earlier.

Do you have any plans converting iRedAdmin to Python3? I can live without admin for a month more if so.

Yes, but I tried again and it is still installed. I even tested the web.py test app again running python2 and no problems during import when running below code

python2 app.py 192.168.1.100:1234

import web

urls = (
    '/', 'index'

It's no problem, everything except the admin is working so I can wait until it is updated to Python3.
