Step 1

apt purge mongodb-org*

It solves the problem «trying to overwrite '/usr/bin/install_compass', which is also in package mongodb-org-tools 4.2.11»

Step 2

apt-get install gnupg curl

mongodb.com/docs/v6.0/tutorial/install-mongodb-on-debian/#import-the-public-key-used-by-the-package-management-system

Step 3

curl -fsSL https://pgp.mongodb.com/server-6.0.asc | \
   sudo gpg -o /usr/share/keyrings/mongodb-server-6.0.gpg \
   --dearmor
