DVD不会安装Ubuntu 12.04
我似乎无法安装我的光驱。 我从这个网站尝试了很多解决方案但没有结果。 我也无法在文件浏览器中看到设备。 驱动器中有一张DVD。 我在HP g60-235dx便携式设备上运行12.04。 我在规格下面有一个链接。 我还将列出我尝试过的内容（我现在可以找到它。）我知道驱动器正在运行，因为在Windows 7崩溃之前我的MBR已经过去了，我正在看电影就好了。 我对linux很新，所以不要以为我什么都知道。 好的，所以这是我尝试过的：
sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list sudo apt-get --quiet update sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring sudo apt-get --quiet update sudo apt-get install libdvdcss2 dmesg | grep sr0 dmesg | grep sr0 （无输出）
apt-get install libdvdnav4 （已安装，并且是最新的）
sudo /usr/share/doc/libdvdread4/install-css.sh ls -l /dev/cdrom /dev/cdrw /dev/dvd /dev/dvdrw /dev/scd0 /dev/sr0 ls: cannot access /dev/scd0: No such file or directory lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/cdrom -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/cdrw -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/dvd -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/dvdrw -> sr0 brw-rw----+ 1 root cdrom 11, 0 Sep 10 03:51 /dev/sr0 wodim --devices wodim: Overview of accessible drives (1 found) : ------------------------------------------------------------------------- 0 dev='/dev/sg1' rwrw-- : 'TSSTcorp' 'CDDVDW TS-L633M' ------------------------------------------------------------------------- sudo lshw optical *-cdrom description: DVD-RAM writer product: CDDVDW TS-L633M vendor: TSSTcorp physical id: 1 bus info: scsi@1:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/sr0 version: 0200 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc sudo lshw | grep cdrom *-cdrom logical name: /dev/cdrom

更新
运行sudo apt-get install –reinstall udisks，注销并重新登录会导致出现错误消息“内部错误”。
运行udisks –mount / dev / sr0并返回驱动器中的光盘：’安装失败：安装错误：安装：在/ dev / sr0上找不到介质’
运行wodim –prcap dev = / dev / sr0，驱动器中没有磁盘返回：

运行sudo lshw -c磁盘与驱动器中的光盘返回：

使用驱动器中的磁盘尝试以下终端命令：
sudo mount -t iso9660 /dev/sr0 /cdrom
或者更简单
sudo mount /dev/sr0 /cdrom
如果您收到“驱动器中没有介质”的错误消息，则最可能的原因是驱动器出现故障。 不幸的是，DVD / CD驱动器比大多数人意识到的要脆弱得多 – 镜片上的一片绒毛或划痕会使它们变得无用。 更糟糕的是，笔记本电脑驱动器上有从设备中弹出的托架上的镜头，使得它们非常容易受到物理损坏。
您可能遇到硬件问题。 尝试手动安装
mount /dev/cdrom /mnt/cdrom cd /mnt ls
我把这篇文章放在另一个答案中，但实际上很简单：
很多人都遇到过这个问题，就像我第一次使用DVD和CD安装一样。 您必须在媒体中为该文件夹创建一个目录。 一定要以root身份运行。
sudo -s cd mkdir /media/[folder_name]如果您有任何关于读/写问题的错误，您将需要chmod
警告，如果您不知道自己在做什么，我建议不要这样做！
sudo -s cd /media chmod ugo+rwx我希望这有帮助！ 主要问题是插入磁盘后驱动器不会自行卸载。 创建目录可以解决此问题。
sudo -s cd mkdir /media/[folder_name]
如果您有任何关于读/写问题的错误，您将需要chmod：
警告，如果您不知道自己在做什么，我建议不要这样做！
sudo -s cd /media chmod ugo+rwx
我希望这有帮助！ 主要问题是插入磁盘后驱动器不会自行卸载。 创建目录可以解决此问题。
收益：
root @ Lexington :(无法访问）/ #cd / media
root @ Lexington：/ media＃ls
root @ Lexington：/ media＃sudo mkdir dvd-drive
root @ Lexington：/ media＃chmod ugo + rwx
chmod：在ugo + rwx之后缺少操作数
