存储库“cdrom://Ubuntu 22.04.1 LTS _Jammy Jellyfish_ - Release amd64 (20220809.1) jammy Release”没有 Release 文件

我最近安装了 Ubuntu 22.04.1 LTS,我发现它与 Jammy Jellyfish 不同。

我收到以下错误:

E: The repository 'cdrom://Ubuntu 22.04.1 LTS _Jammy Jellyfish_ - Release amd64 (20220809.1) jammy 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.

我该怎么办?我刚刚开始学习 Linux 以及如何使用终端。
