I am installing MongoDB on Ubuntu 22.04 LTS using the installation instruction from MongoDB official docs at: (Install MongoDB).
I tried the commands which were mentioned in MongoDB for importing the public key as follows:
curl -fsSL https://pgp.mongodb.com/server-7.0.asc | \ sudo gpg -o /usr/share/keyrings/mongodb-server-7.0.gpg \ --dearmor
Then, I created a list file for for the version of Ubuntu as the following:
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list
But when I run update for updating packages to install MongoDB, I get the following errors and warnings.
W: GPG error: https://repo.mongodb.org/apt/ubuntu <release>/mongodb-org/7.0 Release: \ The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4B7C549A058F8B6B E: The repository 'https://repo.mongodb.org/apt/ubuntu <release>/mongodb-org/7.0 Release' \ is not signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.
