Same error on my SBCs

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

It works with this old drivers in windows. CP2102 doesn't reach high baud rates in linux. Baud rate: 1500000 Data bit: 8 Stop bit: 1 Parity check: none Flow control: none ☑️ CP2104 TTL Tested the original one! ☑️ CP2102 TTL Tested the chinese fake one! with this Driver

Just got this error on a sudo apt update.
