Failing to start Glances as a Service on Raspberry Pi 4

[gaston-arg]

Describe the bug
Cannot start Glances as a service after using the Standard Way installation on a Raspberry Pi 4.

To Reproduce
Steps to reproduce the behavior:

1. I created the glances.service in the /etc/systemd/system/ folder with these contents:

[Unit]
Description=Glances
After=network.target

[Service]
ExecStart=/usr/local/bin/glances -w
Restart=on-abort
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

Then I execute sudo systemctl enable glances.service and finally start the service with sudo systemctl enable glances.service

Expected behavior

Service should be ready to start. However, it doesn't, and the following message appears on the service status:

● glances.service - Glances
     Loaded: loaded (/etc/systemd/system/glances.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Fri 2023-08-11 16:02:16 CEST; 1s ago
    Process: 64295 ExecStart=/usr/local/bin/glances -w (code=exited, status=1/FAILURE)
   Main PID: 64295 (code=exited, status=1/FAILURE)
        CPU: 64ms

Environement (please complete the following information)
Raspbery Pi 4 running Raspbian

Thank you.

Edit:

Not sure if it's actually related or not, but if I try to run Glances from pi user in this case, it works. If I try to run it being root, it fails:

**pi@raspi:/ $ glances --v**
Glances v3.4.0.3 with PsUtil v5.8.0
Log file: /home/pi/.local/share/glances/glances.log
pi@raspi:/ $ sudo su
**root@raspi:/# glances --v**
Traceback (most recent call last):
  File "/usr/local/bin/glances", line 5, in <module>
    from glances import main
ModuleNotFoundError: No module named 'glances'

Hi @gaston-arg

yes it is related.

How do you install Glances on your system ?

[gaston-arg]

I used the Standard Way, so pip I guess.

I have the same issue, running Glances as a service works fine, but when I want to run it as root (sudo glances) I get this:

Traceback (most recent call last): File "/usr/local/bin/glances", line 5, in <module> from glances import main ModuleNotFoundError: No module named 'glances'

I installed through pip, but not sudo pip

[honmashinsei]

I was able to solve it through installing glances with root via pip, but I don't feel comfortable doing that, feels messy (I have two installs now).

("sudo pip install glances")

Have you tried adding User=<your username> to [Service] block in your service file to make it run the same python that was used to install glances? That worked to me.
