compiled but not found, ModuleNotFoundError: No module named 'blueman'

blueman: Latest branche / 2.3.5

Distribution:
Desktop environment: Gnome

• I have consulted the Troubleshooting page and done my best effort to follow.

Hello,
I try to compile it locally on Pop!_OS 22.04 LTS using Gnome 42.9, everything went well, make and make install worked without errors, but I still can't find it hitting me with the error :

Traceback (most recent call last):
File "/usr/local/bin/blueman-applet", line 16, in
from blueman.Functions import create_logger, create_parser, set_proc_title
ModuleNotFoundError: No module named 'blueman'

Just use blueman that is already packaged by ubuntu.

[cschramm]

You installed to /usr/local. Assuming you're using a system provided Python installation, it is not configured to look for packages there.

The one with 22.04 does not offer battery status

[abdelouahabb]

You installed to /usr/local. Assuming you're using a system provided Python installation, it is not configured to look for packages there.

I guess it's a better idea to retrieve Python env and install it there ?

[abdelouahabb]

Here is what happens about Python,
This is the default behavior :
./configure PYTHON=/usr/bin/python

To understand which python it seems, I did :
./configure PYTHON=/usr/local/bin/python3

blueman-manager 
Traceback (most recent call last):
  File "/usr/local/bin/blueman-manager", line 15, in <module>
    from blueman.main.Manager import Blueman
  File "/usr/local/lib/python3.11/site-packages/blueman/main/Manager.py", line 6, in <module>
    from blueman.bluez.Adapter import Adapter
  File "/usr/local/lib/python3.11/site-packages/blueman/bluez/Adapter.py", line 3, in <module>
    from gi.repository import GLib
ModuleNotFoundError: No module named 'gi'

This error proves that it validated the custom python,

So why blueman is not installed into the default python ?

[cschramm]

You need to ./configure at least --prefix /usr if you want to spread it over your system. ...or use a custom Python that also loads from /usr/local if you install it there. PYTHON=/usr/local/bin/python3 would be correct if you actually have one there.

Many other things will break, e.g. you need to configure correct systemd paths, see https://salsa.debian.org/debian/blueman/-/blob/dd9b5402dbc101b836c19966c9be2a1b43992588/debian/rules#L9. The better idea would be to build a Debian package. See that salsa repository for configuration. Or just try a snapshot from https://blueman.cschramm.eu/debian/ where that's already done.

I was going to update the above answer, as I tried to bring a custom deb package, seems its dependecies is 3.11 and not 3.10

The following packages have unmet dependencies:
 blueman : Depends: python3 (>= 3.11~) but 3.10.6-1~22.04 is to be installed
E: Unable to correct problems, you have held broken packages.

Edit : thank you very much, I was able to install the latest version using the repo :

deb https://cschramm.eu/blueman/debian/ python3.10 main
deb-src https://cschramm.eu/blueman/debian/ python3.10 main

Now it seems i get an error with dbus when I click on devices, even if I installed dbus-x11, but blueman-manager works and shows.

Here is what I get (based on other solved issues)

If you did not uninstall what you spread over your system previously, you might have e.g. competing org.blueman.Manager.service in /usr/share/dbus-1/services (package managed) and /usr/local/share/dbus-1/services (configured and installed by you).

[abdelouahabb]

I thought make uninstall will clean the installation ?

[cschramm]

It definitely should, yes.

[abdelouahabb]

and that's what I did ...

NB: in case someone lands here from a Google search, here is how I enabled the battery indicator, as it's experimental feature in bluez

[stephematician]

FWIW: I had a similar problem with ModuleNotFoundError: No module named 'blueman'. I took a slightly different approach.

It appears that sudo make install put the (built) python packages into /usr/local/lib/python3.12/site-packages for me, however the (system) Python interpreter didn't include this folder in its path. Firstly, I checked what paths were being used by Python:

python3 -m site

With output:

sys.path = [
    '/home/<user-name>',
    '/usr/lib/python312.zip',
    '/usr/lib/python3.12',
    '/usr/lib/python3.12/lib-dynload',
    '/usr/local/lib/python3.12/dist-packages',
    '/usr/lib/python3/dist-packages',
]
USER_BASE: '/home/<user-name>/.local' (exists)
USER_SITE: '/home/<user-name>/.local/lib/python3.12/site-packages' (doesn't exist)
ENABLE_USER_SITE: True

So, lazily, I chose to copy the built components to usr/lib/python3/dist-packages:

sudo cp -r /usr/local/lib/python3.12/site-packages/*blueman* /usr/lib/python3/dist-packages

Then everything worked (although I had a missing dependency, gir1.2-nm-1.0, see #963 (comment)) .
