Fetch repository fails

[mats-olov_rustad]

Hello

Today I noticed that sudo apt update returns the following error on a Flat module and a Connect+ module both based on Debian 9 ("stretch"):

Hit:1 http://repository.teamviewer.com/deb stable InRelease
Ign:2 http://raspbian.raspberrypi.org/raspbian stretch InRelease
Hit:3 http://archive.raspberrypi.org/debian stretch InRelease
Hit:4 http://packages.revolutionpi.de stretch InRelease
Hit:5 http://packages.revolutionpi.de stretch-backports InRelease
Err:6 http://raspbian.raspberrypi.org/raspbian stretch Release
404 Not Found [IP: 93.93.128.193 80]
Reading package lists... Done
E: The repository 'http://raspbian.raspberrypi.org/raspbian stretch Release' does no longer have a Release file.
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 know that Debian 9 is a very old version and it is out of support but shouldn't sudo apt update still work without errors even if new packages are available?

With regards

Hi Mats-Olov,

as you can see the repository is from raspberrypi.org. We have no influence on this repository. You might ask this question in the Raspberry Pi forum. But I guess they have not only stopped support but also removed the packages from their repo.

Best regards
Philipp
