apt update stable Release : no longer has a Release file

[mgouin]

Hello,

I would like to know if the repository is broken?

If it is back again, how do I re-enable the "stable Release" repository?

Terminal

xbian@xbian ~ $ sudo apt update
[sudo] password for xbian:
Hit:1 http://deb.debian.org/debian buster InRelease
Ign:2 http://apt.xbian.org stable InRelease
Err:3 http://apt.xbian.org stable Release
404 Not Found [IP: 212.219.56.184 80]
Reading package lists... Done
E: The repository 'http://apt.xbian.org stable Release' no longer has 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.

Thanks
