Here are the standard installation instructions from the website:
wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add - echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list sudo apt-get update sudo apt-get install -y mongodb-org
sudo apt install -y mongodb-org Reading package lists... Done Building dependency tree... Done Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: mongodb-org-mongos : Depends: libssl1.1 (>= 1.1.1) but it is not installable mongodb-org-server : Depends: libssl1.1 (>= 1.1.1) but it is not installable mongodb-org-shell : Depends: libssl1.1 (>= 1.1.1) but it is not installable E: Unable to correct problems, you have held broken packages.
I tried installing the dependency directly but it doesn't seem to have fixed the issue:
