添加 ppa 存储库并获得密钥签名 - 没有有效的 OpenPGP 数据 - 代理问题？

Question

我想得到一个 ppa 密钥签名

我试过

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A258828C     

Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /etc/apt/secring.gpg --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --recv-keys A258828C
gpg: requesting key A258828C from hkp server keyserver.ubuntu.com
gpgkeys: HTTP fetch error 7: couldn't connect to host
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

和

wget -q http://ppa.launchpad.net/panda3d/ppa/ubuntu/dists/lucid/Release.gpg -O- | apt-key add -

gpg: no valid OpenPGP data found

我在代理后面，在 apt.conf 中它配置正确

Acquire::http::Proxy "http://proxy.mycompany.de:3128";

我也试过设置代理

export http_proxy="proxy.mycompany.de:3128"
export https_proxy="proxy.mycompany.de:3128"

Answer 1

尝试

export http_proxy=http://proxy.mycompany.de:3128; export https_proxy=$http_proxy
sudo -E apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A258828C     

Answer 2

您忘记使用 sudo 了吗？

如果你这样做了但失败了，也可以尝试以下方法：

sudo gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /etc/apt/secring.gpg --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv A258828C
