Hello
I have tried to install INDI Web Manager and I have taken all the steps, but when I run the reboot, with the command sudo systemctl status indiwebmanager.service I have the following error: Invalid argument.
I have checked many times all steps, but every time I got the same result.
Can someone help me?
Thank you

on what system are you installing this?

It is installed on raspberry pi 3 b.

I just tested it on Raspbian Jessie on RPI2 and it's working fine. So I'm not sure what your problem is, it probably has nothing to do with INDI web manager and systemd related issue.

Hello.
I have carried out a total control over the installation and the procedure.
Indi web manager works perfectly locally and remotely.
The only problem that remains is related to the start at boot that giving me the following error:
indiwebmanager.service - INDI Web Manager
Loaded: error (Reason: Invalid argument)
Active: inactive (dead)
I would like to know if there is a different way to start the web manager at boot time, because it seems that through the systemctl command in raspberry pi3, this operation does not lead to any results.
Thank you

Post the contents of your /lib/systemd/system/indiwebmanager.service here

[Unit]
Description=INDI Web Manager
After=multi-user.target
[Service]
Type=idle
User=pi
ExecStart=/usr/bin/python /home/pi/servermanager/drivermanager.py
ExecStart=/usr/bin/python /home/pi/servermanager/autostart.py
[Install]
WantedBy=multi-user.target

You ensured all the variables are correct? i.e. your username is pi ? and the path to drivermanager.py is correct?

I checked it many times and everything is correct.

Can you run it manually? If yes, you can put it in any script for startup.

Yes. I can with the command python drivermanager.py.
I try this solution and I hope it works
