After installing Debian Testing "Bullseye" mid March 2020 I got an
error trying to run apt update.
E: The repository 'http://security.debian.org./debian-security
bullseye/updates Release' does not have a Release file.

The offending lines are this.
deb http://security.debian.org/debian-security/ bullseye/updates main

deb http://security.debian.org/debian-security/ bullseye-security main
deb-src http://security.debian.org/debian-security/ bullseye-security main
