mount: wrong fs type, bad option, bad superblock on 192.168.1.105:/home/nfs,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so.
原因是在Ubuntu系统上没有装nfs,所以挂在失败。
解决办法,安装nfs:
sudo apt-get install nfs-common
安装完后即可挂载nfs:
