I get the following on my OP5+ with the 22.04 image when trying to install avahi-daemon

Any ideas?

You installed the flash-kernel package for some reason, please remove it with the below command:

sudo apt-get purge -y flash-kernel

[icojb25]

Thanks a lot. That worked.

Any idea how that would have been installed? I am almost 100% sure i did not install it. I have (had) a clean install of 22.04 server with only Casa OS over the top. I believe I installed avahi myself afterwards.

In any event, thanks a lot.

I cant say there are a lot of factors. But I will keep a general eye out as if a user updates their system after a release and this package is installed I would say that is an issue.

I guess this happened again ... I removed the flash-kernel package which fixed up the problem, but running sudo apt update && sudo apt upgrade -y again results in that package being installed again?

I found the issue Joshua-Riek/linux-rockchip@d245a21, uploading a new kernel now.

Thanks a lot for the fix
