我尝试在多个设备上安装 lubuntu 19.10，但每次我尝试安装时，我都会收到此输出，并收到一条错误消息
External command finished with errors. Command apt-get update finished with exit code 100. Output: Ign:1 cdrom://Lubuntu 19.10 _Eoan Ermine_ - Release amd64 (20191017.1) eoan InRelease Ign:2 cdrom://Lubuntu 19.10 _Eoan Ermine_ - Release amd64 (20191017.1)/New Folder/ Old InRelease Hit:3 cdrom://Lubuntu 19.10 _Eoan Ermine_ -Release amd64 (20191017.1) eoan Release Err:4 cdrom:// Lubuntu 19.10 _Eoan Ermine_ - Release amd64 (20191017.1)/ New Folder/Old Release Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs Reading package lists...

我尝试过创建新分区、linuxswap 和擦除，但没有成功。如果有人有任何建议，我很乐意听取，提前感谢！ 错误信息
