当我运行时sudo apt-get update出现以下错误：
Err:14 https://dl.bintray.com/rabbitmq-erlang/debian bionic InRelease
403 Forbidden [IP: 35.161.110.43 443]
E: Failed to fetch https://dl.bintray.com/rabbitmq-erlang/debian/dists/bionic/InRelease
403 Forbidden [IP: 35.161.110.43 443]
E: The repository 'https://dl.bintray.com/rabbitmq-erlang/debian bionic InRelease' is not 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.
我有以下/etc/apt/sources.list文件内容：
deb http://fr.archive.ubuntu.com/ubuntu/ bionic main restricted
deb http://security.ubuntu.com/ubuntu bionic-security main restricted
deb http://fr.archive.ubuntu.com/ubuntu/ bionic-updates main restricted
我寻找任何解决方案，但找不到。
任何想法？
谢谢
ps：重要的是要知道，我没有图形界面，我只使用命令行
