RockpiE/FAQs

OS

What OS is ROCK Pi E running?

Currently we have Debian Buster, Ubuntu Bionic, etc, running on ROCK Pi E.

Can I ssh to ROCK Pi E running official Debian/Ubuntu?

Yes, you can. The ROCK Pi E is shown as rockpie.local in your local network. Check out the Using SSH page.

Where is the Radxa APT sources list?

Check file /etc/apt/sources.list.d/apt-radxa-com.list.

Some Bluetooth devices are discovered, but failed to connect to them on ROCK Pi E?

One of the reason is the weak signal. To gain a stronger signal, you need an antenna attached to the antenna socket on board.

When I try to run apt update, i get following error:

The reason is the public key used before is expired. You can execute the following command to get the new available.

sudo apt-get install -y wget
export DISTRO=buster-stable
wget -O - apt.radxa.com/$DISTRO/public.key | sudo apt-key add -
sudo apt-get update
