I'm trying to install Node on a Debian Docker container (specifically based off the nginx image). I checked for the correct install script to get version 6.x from nodesource but the curl part of the process errors out once it gets to adding the signing key to the key ring. I'm not particularly experienced with this level of server setup, and searching around for my error somehow didn't give me any good leads.
After apt-get update and upgrade, and installing sudo and curl, I'm trying to execute this:
sudo curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
and eventually always hit this:
## Adding the NodeSource signing key to your keyring... + curl -s https://deb.nodesource.com/gpgkey/nodesource.gpg.key | apt-key add - E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation (23) Failed writing body Error executing command, exiting
Which of these programs are the preferred version? I am assuming these are upgrades or variants of the same thing. I don't recall running into this error on other systems when attempting to install node this way. Would a different version of Debian have one of the
gnupg's installed in an acceptable manner?
