Jerry Jyrer got a reaction from hello_world.c in The repository 'http://apt.armbian.com bionic Release' is not signed.
The work around [trusted=yes] no longer works. As Igor said, Bionic one is not signed.
If you must,
$ sudo apt update -o Acquire::AllowInsecureRepositories=true -o Acquire::AllowDowngradeToInsecureRepositories=true
for the time being while it's being solved (hopefully, it is).

Thanks, Igor. What is the simplest way to shift to mainline? (Preferably without reinstalling.) i.e. Which linux-image package is the correct one for this platform?
Jerry Jyrer got a reaction from Igor in Nanopi M4 on-board bluetooth not found
Thank you Igor. I finally got it work. Basically, follow your guidance:
ExecStartPre=/bin/echo 1 > /sys/class/rfkill/rfkill0/state
ExecStart=/usr/bin/hciattach /dev/ttyS0 bcm43xx 115200 > /dev/null
$ sudo systemctl --no-reload enable nanopi-bluetooth.service
$ sudo systemctl start nanopi-bluetooth.service
BT is working now. : )
Trying to get my generic gamepad to work is another story : (
But at least, it's connected.
