[sungjune]

Hello, I'm a Korean newbie to RPI, and I can't install Hangul from the LXTerminal:

Code: Select all

pi@pi-top:~ $ sudo apt-get install ibus
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package ibus
pi@pi-top:~ $ sudo apt-get install fcitx fcitx-hangul fonts-unfonts-core fonts-nanum
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package fonts-nanum is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Unable to locate package fcitx
E: Unable to locate package fcitx-hangul
E: Unable to locate package fonts-unfonts-core
E: Package 'fonts-nanum' has no installation candidate
pi@pi-top:~ $ 

Do you have other programs or ways or something? Please HELP!!!!!!
