libinput measure ... fails with "Error: No module named 'libevdev'"

[Daniel van Vugt]

$ libinput measure touch-size
Error: No module named 'libevdev'
One or more python modules are missing. Please install those modules and re-run this tool.

I can't find anything by that exact name in Ubuntu that works. And yes I do have a touchpad (Apple Magic Trackpad 2) connected and working.

[Daniel van Vugt (vanvugt)]

This feels like a packaging bug so I haven't reported it upstream yet.

[Daniel van Vugt (vanvugt)]

OK, found it. We're missing python3-libevdev

Not sure why I didn't see that earlier.

[Launchpad Janitor (janitor)]

This bug was fixed in the package libinput - 1.14.1-2

---------------
libinput (1.14.1-2) unstable; urgency=medium

  * control: Fix libinput-tools to depend on python3-libevdev instead of
    -evdev. (LP: #1846323)
