• Errors or warrnings from Solaar:

Describe the bug
After installing Solaar from the PPA I get the following error when running:

solaar: error: Traceback (most recent call last):
  File "/usr/share/solaar/lib/solaar/gtk.py", line 157, in main
    import solaar.listener as listener

    import evdev
ModuleNotFoundError: No module named 'evdev'

To Reproduce
Steps to reproduce the behavior:

1. Run solaar in any terminal emulator

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
Same as issue #1514 but using the PPA mentioned in the documentation. The package should add a dependency to the python3-evdev package.

[pfps]

@antonsoroko Can you investigate?

[antonsoroko]

@dtrunk90 can you show full output of apt show solaar?

b/c i see all the needed dependencies (including python3-evdev):

maybe you did "forced" install of solaar package via dpkg/apt w/o installing dependencies.

try to do apt purge solaar and then apt install solaar to see if you can reproduce the issue.

 Solaar is a Linux device manager for Logitech's Unifying Receiver wireless

 some devices to read battery status.

I've installed it from the official Ubuntu repo before and upgraded after adding the PPA. Maybe it is/was an apt cache issue?

EDIT: Nope, even after a purge it won't install python3-evdev:

@dtrunk90 you are right. it was late night and i misread output of my dpkg -I command.

i downloaded and checked content of all latest debs from PPA:
solaar_1.1.11~ubuntu20.04.1_all.deb - does not have python3-evdev in Depends:
solaar_1.1.11~ubuntu22.04.1_all.deb - does have
solaar_1.1.11~ubuntu23.10.1_all.deb - does have
solaar_1.1.11~ubuntu24.04.1_all.deb - does have

i guess this is a bug of specific version of dpkg-buildpackage program (or other tool related to building) that is used in old Ubuntu 20.04 (which is dpkg-dev = 1.19.7ubuntu3.2).

not sure that this can be fixed on our side. we can ask Debian maintainer to explicitly add python3-evdev to Depends: section (currently it added only to Build-Depends-Indep:, so it is implicit, as i see it), but this is a hack and useful only for old Ubuntu - so i am not sure if it is fine idea.

@skitt - if you know, could you please tell your idea/guess why Depends: can be different for different version of distro? (with the same control file i mean, but with different dpkg-dev package)

[dtrunk90]

Afaik Ubuntu 20.04 is only supported until April 2025 - it's not of a big issue if you have to install the python3-evdev package manually to make it work on that old Ubuntu release. So it's probably better to leave it as it is and don't waste time. But the decision is up to you. Just wanted to report it.

@skitt - if you know, could you please tell your idea/guess why Depends: can be different for different version of distro? (with the same control file i mean, but with different dpkg-dev package)

I don’t know off-hand, my guess is that the difference is the version of dh-python.
