I have tried to perform an update but a repository appears to be missing, see below
debian @ npi:~$ sudo apt update
Hit:1 http ://deb.debian.org/debian buster InRelease
Hit:2 http ://repos.rcn-ee.com/debian buster InRelease
Ign:3 https ://seeed-studio.github.io/seeed_linux_bundle buster InRelease
Err:4 https ://seeed-studio.github.io/seeed_linux_bundle buster Release
404 Not Found [IP: 185.199.111.153 443]
Reading package lists… Done
E: The repository ‘https ://seeed-studio.github.io/seeed_linux_bundle buster Release’ does not 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.
Any help appreciated
