我在 Linux Mint 19.3 中安装光驱时遇到问题。我认为这是一个新问题,因为其他关于该主题的帖子已经过时了。
我的系统:
~$ uname -a
Linux chris-anthemum 5.3.0-51-generic #44~18.04.2-Ubuntu SMP Thu Apr 23 14:27:18 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
尝试将设备安装到 /cdrom:
~$ sudo mount /dev/sr0 /cdrom
mount: /cdrom: no medium found on /dev/sr0.
创建目录 /mnt/dvd 并尝试挂载到该目录后:
~$ sudo mount /dev/sr0 /mnt/dvd
mount: /mnt/dvd: no medium found on /dev/sr0.
笔记- 即使 /dev/sr0 上没有找到介质,我也可以弹出驱动器并打开我的光驱:
~$ eject /dev/sr0
lsblk 将 sr0 显示为 rom 类型:
~$ lsblk

blkid 不显示我的光驱条目:

插入磁盘时lshw显示没有磁盘:
~$ sudo lshw

我的 fstab 文件:

我还已经安装了 libdvd-pkg、vlc 播放器、ubuntu-restricted-extras、libdvdcss2、libdvdnav4 和 libdvdread4。插入任何类型的媒体磁盘(蓝光、DVD 或 CD)时都没有提示,我感觉我在原地踏步,不确定下一步该去哪里。

该消息no medium found
表明您的驱动器当前为空。
如果您不这么认为,这可能是由于:
驱动器中的空介质
驱动器中的介质有缺陷
磨损的激光器
驱动器中的镜头布满灰尘
顺便说一句:这是您从 获得的信息cdrecord -media-info -v
。请注意,我的系统中有多个 CD 驱动器,并且需要指定通常不需要的设备参数:
cdrecord dev=0,1,0 -media-info -v

如果除了缺少介质之外还有其他问题,您将从驱动器收到不同的错误消息。
答案2
使用 CD 启动 PC/笔记本电脑在驱动器中。我的 Mint 也做了同样的事情,如果在启动过程中无法“看到”插入的 CD 驱动器,它甚至不会看到 CD 驱动器。
