I am trying to install mongodb on debian from 10gen repo. I have followed the official guide HERE however i am stuck when trying to add the repo in apt.

The problem is that the signature is invalid. I add the gpg key using the command:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10

and then adding the repo in my sources.d file:

echo 'deb http://downloads-distro.mongodb.org/repo/debian-sysvinit dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list

However, when run apt-get update , i get the error that the signature is invalid.

W: GPG error: http://downloads-distro.mongodb.org/repo/debian-sysvinit dist Release: The following signatures were invalid: 492EAFE8CD016A07919F1D2B9ECBEC467F0CEB10 W: The repository 'http://downloads-distro.mongodb.org/repo/debian-sysvinit dist Release' is not signed. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.

Anyone else having this problem? Is indeed the signature wrong?

The installation guide you are following is:

  • a copy of an old version of the MongoDB documentation but not the official guide (which is hosted on docs.mongodb.com)
  • referring to a historical version of MongoDB: v2.4 was released in 2013 and reached end of life in March, 2016

The public key, package names, and repo paths have changed since MongoDB 2.4.

You should instead be installing a current version of MongoDB using the official guide: Install MongoDB Community Edition on Debian.

Also note: in August 2013 10gen (the MongoDB company) became MongoDB, Inc.
