我是 Linux 新手，本月刚刚安装了 ubuntu 12.04 amd64。我无法使用 texlive2012 iso 映像安装 Texlive。
我用的是推荐命令安装：
mount -t iso9660 -o ro,loop,noauto /your/texlive2012.iso /mnt
但是安装程序无法读取某些文件。iso 没问题，我检查了 md5。
我用存档管理器从 iso 中提取了所有内容，并成功安装。
那么，为什么 mount 不起作用？
使用 furius iso 安装工具，用 Fuse 安装，然后安装。
（第一次安装，安装时出现警告，再次安装，安装成功。）
使用 Loop 安装时，安装失败。
从终端更新了错误消息，使用 furius iso 安装、循环安装。

我确信 iso 没问题。我可以用存档管理器打开它，所有文件都很好。但在安装它之后，甚至存档管理器也无法打开某些文件（在存档管理器中打开 iso 时可以打开这些文件）。
我认为以后我只需使用保险丝即可。

Ubuntu 提供了 TeX Live 软件包：你不需要手动安装。只需使用包管理器
apt-get install texlive-full
编辑
对于 TeX Live 2012，有 [替代存储库][1]
$ sudo apt-add-repository ppa:texlive-backports/ppa
$ sudo apt-get update
$ sudo apt-get install texlive
或者：为什么不使用官方的 tarballhttp://www.tug.org/texlive/acquire-netinstall.html并按照安装说明进行操作？
