Apt error with latest buster image

I just flashed a SD-card with the latest buster image for RockPi-E

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

Err:4 http://apt.radxa.com/buster-stable buster InRelease
  The following signatures were invalid: EXPKEYSIG 5761288B2B52CC90 Radxa <dev@radxa.com>

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

How to fix it?

looks like the keys are expired yesterday 2020-11-22.
I think if radxa team renew them all will work again.

We are working on it. Today it will be fixed.


We have fixed that issue with this guide.

Step 1: Get tool wget

sudo apt update
sudo apt-get install -y wget

Step 2: Edit /etc/apt/sources.list.d/apt-radxa-com.list

deb http://apt.radxa.com/buster-stable/ buster main
deb http://apt.radxa.com/buster-testing/ buster main

Step 3: Get the public key

wget -O - apt.radxa.com/buster-testing/public.key | sudo apt-key add -
wget -O - apt.radxa.com/buster-stable/public.key | sudo apt-key add -

Step 4: Test

sudo apt update
sudo apt install -y linux-4.4-rock-pi-e-latest
