1.I am getting Error as follows.
The installed version of package kernel is not compatible, require 5.4.87-1-d860abdf… while 5.4.87-1-48bd3fe8… is installed.
Do I have to upgrade or downgrade the kernel. How Do I change my kernel to required kernel version.
- I have two systems: on two RPI 3B+ sd cards . I am getting errors

Cannot open device /dev/video0, exiting.
I am new to OpenWrt. I installed the OS Linux OpenWrt 4.14.180 from source downloaded image. Second Image I build on Debian (Ubuntu 18.04) Desktop.
I really need to get the USB Wifi Working on 802.11AC and the camera working.
