Daimajin Posted June 28, 2021 Posted June 28, 2021 Hello, I'm a novice Armbian user (I deployed a number of $8 Rockchip 3328 SBCs as security monitors which for the last few months have been working just fine). I have six identically configured SBCs that I have been regularly updating - about once every few weeks, I run 'sudo apt update' and 'sudo apt upgrade' just to make sure the systems have the latest updates to Armbian and the various software packages I depend on. Up until yesterday, updates were working just fine. Yesterday, I tried to update the SBCs, and all six threw the same errors during 'sudo apt update'. The errors are: E: The repository 'http://apt.armbian.com bionic Release' is no longer signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. I couldn't find any recent discussion of this problem, and past, similar errors that people have reported suggested either accepting the unsigned repository, or switching to an alternative Armbian repository in the UK or China. To be honest, it seems like something changed in the last few weeks (outside of my configuration) and where the SBCs I have are deployed as used as a security system, it seems a bit foolish to just accept an unsigned repository. I could imagine that maybe a key has expired or is misconfigured, but that's just guessing. Is anyone else running into this issue when trying to update Armbian in the last 24 hours? Thanks for any help.
