Ubuntu 24.04中sudo apt-get update执行失败问题求助

大家好，我在Ubuntu 24.04系统上执行sudo apt-get update命令更新软件源时遇到了报错，具体的命令输出如下：

Get:34 http://security.ubuntu.com/ubuntu noble-security/multiverse amd64 c-n-f Metadata [344 B]
Reading package lists... Done  
          
E: The repository 'file:/cdrom noble 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.

有没有大佬能帮我解决这个问题呀？非常感谢！
