W: GPG 錯誤：http://ftp.tw.debian.org squeeze Release: 由于沒有公鑰，無法驗證下列簽名： NO_PUBKEY 07DC563D1F41B907
W: Duplicate sources.list entry http://security.debian.org/ squeeze/updates/main i386 Packages (/var/lib/apt/lists/security.debian.org_dists_squeeze_updates_main_binary-i386_Packages)
原因是公鑰沒有通過驗證，可以通過下面命令解決：
gpg --keyserver keyring.debian.org --recv 07DC563D1F41B907
//后面的07DC563D1F41B907 就是上面提到的 NO_PUBKEY 07DC563D1F41B907中的公鑰，替換成對應的即可。
//紅色字中的1F41B907 是上面公鑰的后八位，也要替換成對應的。
然后重新apt-get update即可。

sudo
su
sudo gedit /etc/sudoers 在root下加入一行
1 # User privilege specification
2 root ALL=(ALL:ALL) ALL
3 r2100 ALL=(ALL:ALL) ALL
time
調整時間現在使用/etc/adjtime,
將第三行從UTC改成LOCAL再到網上更新一下時間，
兩個系統的時間就一致了。
