MongoDB install on ARM?

I'm working to install Mongo on an arm64 machine with no success. Any ideas on what I'm missing? I'm following the steps defined at: https://www.mongodb.com/docs/upcoming/tutorial/install-mongodb-enterprise-on-ubuntu/

The error I see and the steps I followed are below. Any suggestions are appreciated.

root@bamboo8:~# systemctl status mongod
* mongod.service - MongoDB Database Server
     Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)
     Active: failed (Result: signal) since Tue 2022-08-30 17:43:28 EDT; 5s ago
       Docs: https://docs.mongodb.org/manual
    Process: 2946 ExecStart=/usr/bin/mongod --config /etc/mongod.conf (code=killed, signal=ILL)
   Main PID: 2946 (code=killed, signal=ILL)

Aug 30 17:43:28 bamboo8 systemd[1]: mongod.service: Failed with result 'signal'.

The steps I executed to get here were:

wget -qO - https://www.mongodb.org/static/pgp/server-6.0.asc | sudo apt-key add –
 
echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.com/apt/ubuntu focal/mongodb-enterprise/6.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-enterprise.list
sudo apt-get update
sudo apt-get install -y mongodb-enterprise
sudo systemctl start mongod
sudo systemctl status mongod

As a final data point, when I try to execute mongod directly, I get this error:

$ /usr/bin/mongod --version
Illegal instruction

The ILL (Illegal Instruction) exception indicates you are trying to run binaries that aren't fully compatible with your CPU.

As of MongoDB 5.0+, the Minimum Microarchitecture requirement for official arm64 binaries is ARMv8.2-A or later. Some older or lower spec CPUs (like Raspberry Pi or Chromebooks) will not meet this requirement.

Workarounds are:

-
Install a MongoDB server binary compiled with lower microarchitecture requirements. I recommend trying the latest MongoDB 4.4.x arm64 server packages).

-
Build MongoDB server from source specifying an arm64 microarchitecture target compatible with your CPU. For example, using scons ... CCFLAGS=-march=arm8-a or -march=generic (if you don't want to try for any CPU optimisations).
