Canon EOS R6 - Can't change Aperture

[LeMajors]

I can change e.g. ISO or shutterspeed but not the aperture. The camera is set to "M" (Manual Settings) Is this a bug or do I something wrong?

Name the camera Canon EOS R6

libgphoto2 and gphoto2 version gphoto2 2.5.27

To Reproduce gphoto2 --get-config aperture Label: Aperture Readonly: 0 Type: RADIO Current: 6.3 Choice: 0 6.3 Choice: 1 7.1 Choice: 2 8 Choice: 3 9 Choice: 4 10 Choice: 5 11 Choice: 6 13 Choice: 7 14 Choice: 8 16 Choice: 9 18 Choice: 10 20 Choice: 11 22 Choice: 12 25 Choice: 13 29 END

gphoto2 --set-config-index aperture=8 (no output or error message)

gphoto2 --get-config aperture ...the same output as above. That means: Current: 6.3 ...not 16 as expected.

The debug.log is attached: debug.log

Thanks for help,

Marcus

Update: the aperture changes. When I pull out USB I can see the correct settings on the cameras display therefore there may be a bug at gphoto2 --get-config aperture? This still shows Current: 6.3

the EOS R reporting of aperture was not handled correctly in 2.5.27, update to 2.5.29 please and test again...

Thanks for this info. Unfortunately I don't know much about make, etc. I'm using a Raspi 4B and tried this tutorial: https://www.e-techno-tutos.com/wp-content/uploads/2021/05/Instructions.pdf

Now the version of gphoto2 is 2.5.28.1, libphoto2 is still 2.5.27...

If you have a noob tutorial for the update-process on the RPI I would be glad to get a link. Otherwise I will live with this bug until a noob-friendly "apt get install..." is out.

there is a gphoto2-updater script, but not sure if it would work for you. Otherwise sadly you have to wait :/

[LeMajors]

Yes! That solves all problems. The script updatet my pi to gphoto2 2.5.28 and libgphoto2 to 2.5.29.1 and now it works! Many thanks!!
