MongoDB GPG - Invalid Signatures

Question

I\'m installing MongoDB on an Ubuntu 14.04 machine, using the instructions at: https://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/

So I run:

Answer 1

It seems version 3.2.1 has been released on 11/Jan/2016, and the packages signature is bad since this moment. The packages signature were fine the day before.

refs: https://jira.mongodb.org/browse/SERVER/fixforversion/15908/?selectedTab=com.atlassian.jira.jira-projects-plugin:version-summary-panel

You can either add the --force-yes option, or wait for a few hours that the mongodb team sees and fixes the issue.

There is already a ticket there: https://jira.mongodb.org/browse/SERVER-22144

Answer 2

I also faced this issue when installing MongoDB 4.0 on Ubuntu 16.04. So I did.

1. sudo rm /etc/apt/sources.list.d/mongodb*.list - remove any existing file for MongoDB

2. sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv E52529D4 - add the key

3. sudo bash -c 'echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" > /etc/apt/sources.list.d/mongodb-org-4.0.list' - create a new MongoDB repository list file

Now, Complete the installation with an update of repositories then install MongoDB, enable the mongod service and start it up, and last, check your MongoDB version:

sudo apt update
sudo apt install mongodb-org

systemctl enable mongod.service
systemctl start mongod.service

mongo --version

Answer 3

I had the same problem, so I did:

root@skarabi:~# apt remove mongodb-org

Then:

root@skarabi:~# sudo rm /etc/apt/sources.list.d/mongodb*.list

After :

root@skarabi:~# apt update

Answer 4

You don't need to reinstall the mongo packages, but just change the key as following:

List the keys to confirm it is expired:

apt-key list | grep "expired:"

Replace the key:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 0xd68fa50fea312927

The number 0xd68fa50fea312927 is the current valid key id (expires at 2019-10-09), as you can check here.

Answer 5

Actually, the following is very important to solve the problem

$ sudo rm /etc/apt/sources.list.d/mongodb*.list

Answer 6

Sounds like you need to redo the installation steps for MongoDB. First,remove any existing repository file for MongoDB. Do as below.

$ sudo rm /etc/apt/sources.list.d/mongodb*.list

Next, add the key: (without the key, the repository will not load).

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927

Now, create a new MongoDB repository list file:

$ echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

After adding the repository details, we need to update the packages list.

$ sudo apt-get update

Now install MongoDB.

sudo apt install mongodb-org

Hope this helps !
