尝试更新有关Debian Etch安装的某些存储库,并通过运行“ apt-get update”得到以下错误
W: GPG error: http://www.debian-multimedia.org etch Release: The following signatures couldn't be verified because teh public key is not available: NO_PUBKEY 07DC563D1F41B907
W: You may want to run apt-get update to correct these problems
具有讽刺意味的是,它指示我运行apt-get update是一个不错的选择。
