I tried to install mongoDB in my OS so I followed these steps:
1- “wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -”
output

pub   rsa4096 2021-02-16 [SC] [expires: 2026-02-15]

uid           [ unknown] MongoDB 5.0 Release Signing Key <packaging@mongodb.com>

2- “echo “deb MongoDB Repositories buster/mongodb-org/5.0 main” | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list”
output:

deb http://repo.mongodb.org/apt/debian buster/mongodb-org/5.0 main

3- after sudo apt-get update:
“sudo apt install mongodb-org”
output:

mongodb-org is already the newest version (5.0.2).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 mongodb-org-database : Depends: mongodb-org-server but it is not going to be installed
                        Depends: mongodb-org-mongos but it is not going to be installed
 mongodb-org-tools : Depends: mongodb-database-tools but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

4- “sudo apt --fix-broken install”

Hi chris,
I already do that and now I get this error when I try to check my mongo availability with :

sudo systemctl status mongod

output:

I tried many solution such as:

sudo chown -R mongodb:mongodb /var/lib/mongodb
chown -R mongodb:mongodb /var/lib/mongodb

but mongodb still inactive

Hi there,
I fix my issue, by uninstall and reinstall mongoDB
