我使用 mkusb 创建了一个具有持久内存的 Linux Lite Live。我将持久内存设置为100%。
我需要从 Linux Lite Live 中删除 cdrom 存储库，这样我就不必因诸如此类的消息而烦恼
Updating from such a repository can't be done securely, and is therefore disabled by default.
当我尝试更新软件包时。
问题是，当我在软件和更新中删除或禁用 cdrom 存储库时，它会在重新启动后恢复启用状态。这意味着我每次sudo apt-get update重启后必须使用时都必须将其删除。它真的让我很烦。
我已经尝试将其删除在sources.list文件中。删除的行在重新启动后会恢复。
我需要做什么才能让它从我的存储库列表中永远消失？
输出sudo apt-get update：
Ign:1 cdrom://Linux Lite 5.0 - Release amd64 dists/ InRelease
Err:2 cdrom://Linux Lite 5.0 - Release amd64 dists/ Release
Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs
