Installing Heroku Toolbelt on Ubuntu through a proxy

Question

I'm trying to install the Heroku Toolbelt on an Ubuntu machine that's connected to the internet through a proxy. I'm pretty new to Ubuntu and its settings but I managed to get connected to the internet fine. Internet seems to be working fine for just browsing and getting updates via apt-get is always successful and curl commands return what's expected.

When I try to run the command on the Heroku Toolbelt site:

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

I get some errors:

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

The most noticeable error is probably just

What am I missing?

Answer 1

I just had the same problem when installing heroku toolbelt behind proxy:

The core of the problem is this:

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

You will notice, that the next time that you run apt-get update you will obtain the same message. It seems that ubuntu is not able to aquire the public key of heroku package repository.

To get over this you can attach the public key manually as described here: 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 -

After this the installation script will run OK.
