几天前，我在笔记本电脑上安装了 Debian。今天我想安装 Sublime Text 3，并想将其存储库添加到我的信任存储库中。输入
sudo add-apt-repository ppa:webupd8team/sublime-text-3
在我的终端中，我得到以下输出：
gpg: keybox '/tmp/tmpninimrhg/pubring.gpg' created
gpg: /tmp/tmpninimrhg/trustdb.gpg: trustdb created
gpg: key C2518248EEA14886: public key "Launchpad VLC" imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg: imported: 1
gpg: no valid OpenPGP data found.

此外，当我运行时apt-get update，我得到如下输出：
W: Target DEP-11-icons (main/dep11/icons-64x64.tar) is configured multiple times in /etc/apt/sources.list:3 and /etc/apt/sources.list:5
有人能帮帮我吗？谢谢！
答案1
由于密钥不在 Debian 密钥服务器上可用，而在 ubuntu 密钥服务器上可用。因此，您需要传递一个选项来专门查询 ubuntu 密钥服务器，然后它才会按预期工作。
命令是：
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C2518248EEA14886
