dbus installation problem

[vzaliva]

Describe the bug

"vpn_status" module does not work as expected. It just shows "vpn_status" text.

Your py3status version

py3status version 3.52 (python 3.11.4) on i3

To Reproduce

Add module "vpn_status" Run py3status -d -l log.txt

Expected behavior

to show VPN status. Instead in the log file I see the following error:

2023-08-07 10:30:11 INFO loading module "vpn_status" from py3status.modules.vpn_status
2023-08-07 10:30:11 INFO Module `vpn_status` could not be loaded (No module named 'dbus')
2023-08-07 10:30:11 INFO No module named 'dbus'

Additional context py3status installed via :

I have following system-wide packages installed:

apt install python3-dbus sudo apt install python-dbus-dev

It was the case of missing dependencies. The following commands helped:

pipx inject py3status dbus-python
sudo apt install libcairo2-dev libgirepository1.0-dev
pipx inject py3status pygobject

I think package specification in pip needs to add dependencies for dbus-python and pygobject

[lasers]

If you clicked on (red/error) vpn_status, it should expand with a message similar to your error log. As for missing dependencies, I see this is already documented in vpn_status module.

dbus-python: to interact with dbus pygobject: which in turn requires libcairo2-dev, libgirepository1.0-dev

This is necessary only for vpn_status. I don't think we should add module dependencies to py3status and if we do, there would be several unwanted dependencies. Users should install them manually.

Alternatively, we split up py3status modules into individual packages with additional dependencies. Meh.
