从 ISO 安装 TeXLive

我texlive2017-20170524.iso已从http://muug.ca/mirror/ctan/systems/texlive/Images/下载。

并尝试使用“使用存档安装程序打开”（通过右键单击它）和“使用 --> 磁盘映像安装程序打开”来安装它

他们都成功地安装了。

当我cd到安装位置并运行./install-tl（也尝试过./install-tl）时，它给了我这个错误：

TeXLive/TLUtils.pm did not return a true value at ./install-tl line 54.
BEGIN failed--compilation aborted at ./install-tl line 54.

这是前 60 行install-tl

我还尝试将内容复制到我的硬盘驱动器（因此它不再是 ISO 格式），因为在直接从 ISO 运行应用程序之前我遇到了问题。它仍然给我上述错误。

问题：如何使用 将 TeXLive 安装到我的系统texlive2017-20170524.iso？
（我宁愿使用离线安装程序而不是sudo apt-get install texlive）

这是我在终端上看到的：

Me@Computer:~/Desktop$ cd ~/Desktop
Me@Computer:~/Desktop$ mkdir mountpoint
Me@Computer:~/Desktop$ sudo mount -o loop texlive2017-20170524.iso mountpoint
[sudo] password for Me: 
mount: /dev/loop0 is write-protected, mounting read-only
