Also had the same problem and the above answer did help tremendously, but I found a couple stuff missing. My issue was also of the processor compatibility and required to uninstall the version I had installed and install a earlier version of MongoDB.

Here are the steps I followed, that did it for me

First, Uninstall the MongoDB version you had installed, requires removing the used repo from the sources.list, otherwise it will just keep installing that one (or latest version), even after uninstalling it. So to remove the repo from the sources.list follow these steps:

  • List the contents of sources.list directory using

    ls -l /etc/apt/sources.list.d/

  • Remove the repo(s) using the command

    sudo rm /etc/apt/sources.list.d/<repo_name>

Once the repo(s) are removed, uninstall MongoDB. Use these commands:

sudo apt purge "mongodb-org*"
sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb

After uninstalling MongoDB, you might want to update the package list, so use

sudo apt update

From here onward, you can follow the steps for installing the lower version of MongoDB you want as outlined in the manual. Just make sure you select the version you want.

If it happens that the earlier version you get to also throws the same error, repeat the process, going to an earlier version still.

Downgrade to 4.4

first, remove MongoDB

sudo apt-get purge mongodb-org*

sudo rm -r /var/log/mongodb

sudo rm -r /var/lib/mongodb

sudo rm -rf /etc/apt/sources.list.d/mongodb-org-5.0.list

install MongoDB 4.4

wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt- 
key add -

This worked for me seems to be a hardware problem, especially the CPU

i had the same problem with the same message. Seems to be a problem of processor compability.

Found this post https://www.mongodb.com/community/forums/t/mongodb-5-0-cpu-intel-g4650-compatibility/116610

Check if your pocessor has the flags mentioned in the answer with the command:

cat /proc/cpuinfo

if not, you can try with an older version of mongo. In my case my processor can't handle mongo4.4, but installed mongo4.2 and works fine, but depends of your processor and SO.
