每当我收到来自security.debian.org的升级包时，我得到以下错误：
WARNING: The following packages cannot be authenticated! apache2 apache2-mpm-prefork apache2.2-common ... Install these packages without verification [y/N]? E: Some packages could not be authenticated 我在OpenVZ容器中运行Debian 6。 我在/etc/apt/sources.list中有以下行：
deb http://security.debian.org squeeze updates/main updates/contrib
我有安装debian-archive-keyring并且是最新的。
OpenVZ随附的sources.list模板configuration错误。 运行以下来更正它：
sed -i 's#security.debian.org squeeze updates/main updates/contrib#security.debian.org/ squeeze/updates main non-free contrib#' /etc/apt/sources.list apt-get update
