所以我继续这样做：
# apt-get update Get:1 http://ftp.us.debian.org etch Release.gpg [1032B] Hit http://ftp.us.debian.org etch Release (...bunch more of this elided...) Hit http://ftp.us.debian.org etch/contrib Sources Fetched 68.8kB in 1s (37.4kB/s) Reading package lists... Done W: There is no public key available for the following key IDs: 9AA38DCD55BE302B W: GPG error: http://ftp.us.debian.org etch Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9AA38DCD55BE302B W: You may want to run apt-get update to correct these problems
显然我不能运行apt-get update,因为apt-get要求我运行apt-get update来解决这个问题,这是令人不快的.我该如何纠正？
解决方法
尝试这样做并再次运行apt-get：
apt-key update
apt-key is a program that is used to
manage a keyring of gpg keys for
secure apt. The keyring is kept in the
file /etc/apt/trusted.gpg (not to be
confused with the related but not very
interesting /etc/apt/trustdb.gpg).
apt-key can be used to show the keys
in the keyring,and to add or remove a
key.

如果这不起作用,请尝试：
gpg --keyserver wwwkeys.eu.pgp.net --recv-keys 9AA38DCD55BE302B apt-key add /root/.gnupg/pubring.gpg apt-get update
