I’ve followed the tutorial and it doesn’t want to work. Probably something I’ve done wrong again. I followed: > **[How to setup a Raspicam?](https://crowsnest.mainsail.xyz/faq/how-to-setup-a-raspicam#troubleshooting)** And the camerapi don’t work. When I use : libcamera-hello --list-cameras No camera avaible. ---

When I restarted my printer after 3 or 4 month I just made update klipper with the update manager section on webinterface After I loose my camerapi. I look on the internet, I try to change just the lines on moonraker.conf: [update\_manager crowsnest] type: git\_repo path: ~/crowsnest origin: [GitHub - mainsail-crew/crowsnest: Webcam Service for multiple Cams](https://github.com/mainsail-crew/crowsnest.git) install\_script: tools/pkglist.sh It’s not work. I followed your suggestion: > **[Upgrade from v3 to v4](https://crowsnest.mainsail.xyz/faq/upgrade-from-v3-to-v4)** > > There is a huge different between Crowsnest v3 and v4. Unfortunately, it also means that there are major breaking changes, and you'll need to do some manual steps to upgrade. Maybe I made an error at this point: `do you want to remove crowsnest.conf` \> answer with `n` for “No” I think I select : y I follow this tutorial (2x): > **[How to setup a Raspicam?](https://crowsnest.mainsail.xyz/faq/how-to-setup-a-raspicam#troubleshooting)** I have add : camera\_auto\_detect=1 at the bottom of this file. But it’s don’t work And that’s it. ---

I found an solution Delete old webcam in webcam section in interface setting If you have create a file for install a cam before v4 of crowsnest, delete old file webcam.conf in machine section. Delete all old section crowsnest in moonraker.conf in machine section. Uninstall crowsnest with putty (set yes for uninstall old crowsnest.conf too): > **[Uninstall](https://crowsnest.mainsail.xyz/setup/uninstall)** Install crowsnest: > **[Installation](https://crowsnest.mainsail.xyz/setup/installation)** Go to crowsnest.conf file and configure your file: > **[\[cam\] section](https://crowsnest.mainsail.xyz/configuration/cam-section)** Chek your crowsnest.log file to find your device and add this line in your cowsnest.conf: Detected ‘libcamera’ device → xxxxxxxxxxxxxxxxxxxxxxxxxxx I hope this help you
