Argon One fan control installation on Ubuntu v21.04 with solution

[HugoFroh]

Here are the steps I took to get the .deb package to work on ubuntu V21.04.
sudo apt update
sudo apt upgrade
User "pi" will be created
sudo adduser pi
The group "gpio" will be created
sudo addgroup gpio
The package for gpio will be installed
sudo apt install python3-lgpio
Save the file "argon1_0.2.1_all.deb" from the github page https://github.com/spapadim/argon1 in the directory "Downloads" on the raspberry pi. Change to the "Downloads" directory.
cd Downloads
Confirm the queries with Yes and OK
sudo apt install ./argon1_0.2.1_all.deb
sudo apt install rpi.gpio-common -> Has already been up to date with me
Add users to the "dialout" group
sudo adduser {USER} dialout -> {USER} = current user
sudo adduser argonone dialout
sudo adduser pi dialout
cd /lib/python3/dist-packages/argonone/
sudo nano __init__.py Open file with editor
Important!! Make the change according to Post # 14 and save the file under the same name.
reboot
After the restart, enter the following command to check
sudo systemctl status argonone -> quit with q
There should be a green dot in the output and no error message

With that the demon runs!
The function can now be tested with the argonctl {xyz} commands, see original description.
Have fun testing.

I'm trying to get it working on Ubuntu 20.04 following your guide, but the crucial step is missing as comment 14 is not here...
