MongoDB 3.6 is relatively old (EOL/EOS April 2021) and not recommended for production use unless the case requires it (the latest is 6.1 as of reading this text)

If you need it only for some testing to not pollute your Ubuntu 22 installation I would recommend to install it manually in some folder separate for your testing only, described in following steps:

1. Download the 3.6 package from the archive(example 3.6.22):

   https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-ubuntu1804-3.6.22.tgz
   

2. Uncompress the binary files in some folder ( example /database/bin ) .

3. If needed download the expected ssl libraries and extract the libcrypto package to expected location:

   http://security.ubuntu.com/ubuntu/pool/main/o/openssl1.0/

   sudo cp libcrypto.so.1.0.0 /usr/lib/

4. Prepare some nice config file and store in /database/bin/mydb.conf :

   storage:
    dbPath: /database/db1
    directoryPerDB: true
    journal:
      enabled: true
    wiredTiger:
      engineConfig:
        cacheSizeGB: 1
        directoryForIndexes: true
   
   systemLog:
     destination: file
     logAppend: true
     path: /database/log/db1.log
   
   net:
     port: 20000
     bindIp: 127.0.0.1
   
   
   processManagement:
     fork: true
   

5. Create the necessary directories and start the mongod binary:

   mkdir -p /database/db1
   mkdir -p /database/log 
   /database/bin/mongod --config mydb.conf
   

6. You can access the database as follow:

   /database/bin/mongo --port 20000
   

Answer 2

To install the latest stable version, issue the following

sudo apt-get install -y mongodb-org

To get rid of "E: Unable to correct problems, you have held broken packages " open the terminal with "Ctrl + Alt + T" and type:

sudo apt install --fix-missing

Hope that helps...
