Debian Etch에서 apt-get update시 public key 오류

apt-get update를 할 때.. (혹은 dselect에서 update..)

W: There are no public key available for the following key IDs:
A70DAF536070D3A1
W: You may want to run apt-get update to correct these problems

위와 같은 오류 발생..
정확히는 모르겠으나 gpg-key를 변경했다는 것 같으니 바꿔주자..

# gpg --keyserver wwwkeys.eu.pgp.net --recv-keys A70DAF536070D3A1
gpg: directory `/root/.gnupg' created
gpg: new configuration file `/root/.gnupg/gpg.conf' created
gpg: WARNING: options in `/root/.gnupg/gpg.conf' are not yet active during this run

# apt-key add /root/.gnupg/pubring.gpg
OK

A70DAF536070D3A1 대신 위 오류 메시지에 키값을 입력해주면 된다..

이제 정상적인 업데이트가 가능하다.
