Just got this error on a

sudo apt update.

 

I'm experiencing the same issue on my Orange Pi 5 running Armbian 25.11.2 noble (Ubuntu 24.04).
 

Error:

E: The repository 'http://apt.armbian.com noble Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

 

What I've tried:

• Downloaded and installed the armbian.key multiple times:

wget https://apt.armbian.com/armbian.key gpg --dearmor < armbian.key 
sudo tee /usr/share/keyrings/armbian.gpg > /dev/null sudo chmod go+r /usr/share/keyrings/armbian.gpg

• Copied the key to both locations:

sudo cp /usr/share/keyrings/armbian.gpg /etc/apt/trusted.gpg.d/armbian.gpg

• Configured the repository using both .list and .sources formats

The problem: The repository keeps redirecting to different mirrors (armbian.atomonetworks.com, armbian.lv.auroradev.org, etc.) and none of them have valid InRelease or Release.gpg files:

$ curl -I https://armbian.atomonetworks.com/apt/dists/noble/InRelease HTTP/2 404

 

Workaround: The github.armbian.com/configng repository works fine, but the main apt.armbian.com repository appears to have infrastructure issues with signature files missing on all mirrors.

 

Is this a known issue?

 

System info:

• Distribution: Armbian 25.11.2 noble
• Ubuntu version: 24.04 LTS
• Architecture: arm64
• Device: Orange Pi 5

 

Same error on my SBCs

Same error here on a bananapi m5 for debian bookworm

The repository 'http://apt.armbian.com bookworm Release' is no longer signed

with this definition :

deb [signed-by=/usr/share/keyrings/armbian.gpg] http://apt.armbian.com bookworm main bookworm-utils bookworm-desktop

 

 

Same, using a couple of Orange Pi Ones

mirrors/repo are degraded at the moment. We're aware and working on it.

@Werner Thank you for handling this. As a quick fix for developers making new images: use ./compile.sh SKIP_ARMBIAN_REPO=yes

Thanks @Werner this is fixed, it works.

In my case auto selected mirror is fi.mirror.armbian.de .
