ubuntu - 通过代理在 Ubuntu 上安装 Heroku Toolbelt

Question

我正在尝试在通过代理连接到互联网的 Ubuntu 机器上安装 Heroku Toolbelt。我对 Ubuntu 及其设置还很陌生，但我成功地连接到了互联网。 Internet 似乎工作正常，仅通过 apt-get 浏览和获取更新总是成功的，curl 命令返回预期的结果。

当我尝试在 Heroku Toolbelt 站点上运行命令时:

wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh

我得到了一些错误:

me@mypc-vb:~/Documents/stuff$ wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh

我错过了什么？

Answer 1

我在代理后面安装 heroku toolbelt 时遇到了同样的问题:

问题的核心是这样的:

GPG error: http://toolbelt.heroku.com ./ Release: The following
signatures couldn't be verified because the public key is not
available: NO_PUBKEY C927EBE00F1B0520

您会注意到，下次运行 apt-get update 时，您会收到相同的消息。看来 ubuntu 无法获取 heroku 包存储库的公钥。

要解决这个问题，您可以按照此处所述手动附加公钥: http://en.kioskea.net/faq/809-debian-apt-get-no-pubkey-gpg-error

gpg --keyserver pgpkeys.mit.edu --recv-key  C927EBE00F1B0520 
gpg -a --export C927EBE00F1B0520 | sudo apt-key add -

在此之后安装脚本将正常运行。
