解決 ubuntu 掛載 nfs 時出現的錯誤!!

用 ubuntu 掛載 linux nfs server時, 出現下列錯誤 :

# mount fileserver:/disk1/home /home/
mount: wrong fs type, bad option, bad superblock on scorpius:/disk1/home,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount. helper program)
In some cases useful info is found in syslog – try
dmesg | tail or so

執行下列指令後, 就可以順利掛載解決
sudo aptitude install nfs-common
