无法挂载任何 ISO 映像

我正在运行内核版本为 4.0.7-2 的 Arch Linux，但无法安装任何 ISO 映像。我下载了 Arch live 镜像和命令

mount archlinux-2015.08.01-dual.iso /media/iso

给出以下错误：

mount: wrong fs type, bad option, bad superblock on /dev/loop1,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

whiledmesg | tail给了我这个：

即使重复执行该命令后，这也不会改变，因此可以肯定地说它实际上并没有在系统日志中写入任何内容。

执行fuseiso archlinux-2015.08.01-dual.iso /media/iso给了我

init: wrong standard identifier in volume descriptor 17, exiting..

最后，执行mount -o loop -t auto archlinux-2015.08.01-dual.iso /media/iso会出现与上面相同的错误，但实际上会在 dmesg 中添加以下错误：

UDF-fs: warning (device loop1): udf_fill_super: No partition found (2)

无论我尝试安装哪种 ISO 映像，都会发生这种情况。任何人都知道可能导致此问题的原因是什么？

答案1

可能是 .iso 文件的权限问题；检查您是否拥有该文件。您可以使用 ls -l 命令（列出有关文件的信息）来查找文件/目录所有者和组名称。

此外，与 mount 命令相关，您始终可以指定文件系统类型：

mount -t iso9660 archlinux-2015.08.01-dual.iso /media/iso

Fuseiso 不适用于已安装的文件。尝试卸载该文件：

umount /media/iso  ( or force unmount with: umount -f /media/iso )

然后再次执行命令：

fuseiso archlinux-2015.08.01-dual.iso /media/iso

稍后编辑

我对文件格式很好奇，因此我下载了相同的 arch 发行版文件并使用以下命令安装在我的 RHEL 6.6 上：

mount -t iso9660 -o loop /file_location/archlinux-2015.08.01-dual.iso /media/iso
