Debian：add-apt-repository 找不到 openpgp 密钥，然后出现异常/错误

Question

几天前，我在笔记本电脑上安装了 Debian。今天我想安装 Sublime Text 3 并想将他们的 repo 添加到我信任的 repo 中。进入时

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.

    os.unlink(name, dir_fd=topfd)
FileNotFoundError: [Errno 2] No such file or directory: 'S.gpg-agent.extra'

另外，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

有人可以帮助我吗？谢谢！

由于该密钥在 debian 密钥服务器上不可用，但在 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，然后它将按预期工作。

命令是： apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C2518248EEA14886
