Xubuntu 18.04.2 - USB光盘-RW不会写

Question

我在Mini上运行Xubuntu18.04.2。因为内部的DVD-RW驱动器死了，我买了一个外部的USB光盘和DVD读取驱动器。当我放入一个空白的CD-R时，空白磁盘显示在桌面上.但是我的烧录程序Xfburn不会识别驱动器，也不会给它写信。所附的图形显示了我的磁盘程序为驱动器显示的内容：

基于其他论坛上类似的帖子，我从命令提示中提取了以下信息。有没有人知道我如何激活设备的写功能，这样它就可以刻录CD了？(我知道这个驱动器不能像上面说的那样写DVD。)谢谢!

-更新: 7/13/2019：

操作Xfburn的The用户需要对刻录机的设备文件进行有效的读写权限(此处为/dev/sr0)。你的截图上写着“只读”。驱动器必须能够识别介质。你的截图上写着“媒体-”Xfburn使用libburn，而不是cdrecord。对libburn程序的检查建议，插入空白介质: cdrskin -v dev=/dev/sr0 -toc --请发布结果。-托马斯·施密特昨天

我尝试运行cdrskin，并得到以下消息:命令“cdrskin”未找到，但可以安装：

    sudo apt install cdrskin

我这么做了。它安装了鸡皮。磁盘程序仍然显示/dev/sr0 0(只读)。然后我做了：

    msgeek@Navi2:~$ cdrskin -v dev=/dev/sr0 -toc

Please编辑您的问题并添加命令组的输出。很可能您的帐户中缺少cdrom组。-昨天

我这样做了，得到了这样的结果: msgeek adm拨号传真cdrom软盘磁带sudo音频dip视频plugdev netdev lpadmin扫描器脉冲访问sambashare

所以，我没有cdrom的小组。我该怎么加？同时。

The输出ls /dev/sr0、getfacl /dev/sr0和-l的输出将进一步帮助澄清权限情况。-托马斯·施密特昨天

    msgeek@Navi2:~$ ls -l /dev/sr0, of getfacl /dev/sr0
    ls: cannot access '/dev/sr0,': No such file or directory
    ls: cannot access 'of': No such file or directory
    ls: cannot access 'getfacl': No such file or directory
     brw-rw----+ 1 root cdrom 11, 0 Jul 13 21:27 /dev/sr0

    whoami gives the result msgeek - the person who set up the computer for me.

我对Linux非常陌生，所以希望您能提供一些建议，说明从哪里开始。提前感谢！

-更新2019年7月15日:许可情况看上去不错。("of“意为文本”或“和"getfacl”是获取ACL的命令。无论如何，"cdrom“组的成员身份允许您打开驱动器读写。)克德斯金愿意烧掉CD-R。Xfburn也应该是。如果你选择动作“烧伤图像”会发生什么？菜单窗口是否在“燃烧装置”下显示燃烧器的名称？("Optiarc CRX890A")如果是这样的话，那么您就被显示的“组合”操作弄错了。如果没有，那我就没有主意了。-托马斯·施密特昨天

我明白。我也会打字。嗯，由于我没有组cdrom，而且没有人告诉我如何创建或安装它，我需要更多的信息。

所以我这样做了: msgeek@Navi2:~$ getfacl /dev/sr0 getfacl:从绝对路径名称# file: dev/sr0 # owner: root # group: cdrom user::rw- user:msgeek:rw- group::rw-掩码：：rw-other：--所以这个命令建议我的系统上有组cdrom。所以我再次运行了指挥小组，我得到了..。

    msgeek adm dialout fax cdrom floppy tape sudo audio dip video plugdev netdev lpadmin scanner pulse pulse-access sambashare

所以现在我的组中有cdrom。磁盘显示仍然没有写功能。我回去跑了：

    msgeek@Navi2:~$ getfacl /dev/sr0
    getfacl: Removing leading '/' from absolute path names
    # file: dev/sr0
    # owner: root
    # group: cdrom
    user::rw-
    user:msgeek:rw-
    group::rw-
    mask::rw-
    other::---

像泥一样干净。运行命令cdrskin -v dev=/dev/sr0-toc将提供相同的结果。我输入了命令burn映像并得到了以下命令：

    msgeek@Navi2:~$ burn image

    Command 'burn' not found, but can be installed with:

    sudo apt install burn

所以我去安装了它。现在我尝试命令burn映像和.

    msgeek@Navi2:~$ burn image
    Traceback (most recent call last):
      File "", line 1, in 
      File "/usr/lib/python2.7/dist-packages/burnlib/burn.py", line 42, in 
        import audio
      File "/usr/lib/python2.7/dist-packages/burnlib/audio.py", line 28, in 
        import eyeD3
    ImportError: No module named eyeD3

因此，我运行磁盘程序，它显示了一些略有不同的内容，但仍然显示了磁盘的“只读”。

谢谢你的帮助托马斯。我和以往一样感到困惑，尽管也许已经取得了进展。(我不知道这些安装对我的系统造成了什么影响，但它似乎仍然在工作。)如有任何来自您或其他帮助者的其他建议，我们将不胜感激。我会给你我的配方的酸奶油咖啡蛋糕，如果你能得到驱动器写，我发誓！

好吧，我买了一个不同的外接USB/DVD录音机。我发现有时候xfburn会偶尔工作，但是Brasero似乎更可靠。谢谢你在这方面的帮助，请试试蛋糕配方。
