I have a Raspberry Pi 5 with 8GB of RAM.
I followed the instructions on the Internet and built and installed both libcamera and rpicam-apps.
rpicam-apps work flawlessly on Raspberrypi OS and, moreover, they work without sudo.
However, on Ubuntu rpicam-apps require sudo to work and to detect the camera.
The stange thing on Ubuntu was that just after compilation and installation of libcamera and rpicam-apps the latter worked without sudo just until the first reboot. After the reboot rpicam-apps stopped working without sudo.
I checked the files in /dev both on Raspberrypi OS and Ubuntu and noticed that on Raspberrypi OS ACLs are applied automatically on every reboot; whereas on Ubuntu files in /dev don’t have ACLs after reboot even though the output of udevadm info /dev/video0 indicates that user access tags are present. Moreover, manual ACL assignment with sudo /usr/bin/setfacl -m u:$USER:rw /dev/video0 does’t fix the access problem: rpicam-apps still can't detect the camera without sudo.
Here is the output of sudo camera-bug-report on Raspberrypi OS and Ubuntu.
I need to use the camera with ROS and need both Ubuntu and user access.
Does anyone have any thoughts about how to fix the camera user access problem on Ubuntu?
