I have a quick question: suppose that, as root (or a user with high privileges), I install some package by running sudo apt-get install somepackage. Is there a way to block other users from launching somepackage in Ubuntu/Linux Mint? If so, can it be done with packages built from source as well?
Any help will be appreciated :)

Can you be more specific about why you would want to do this? This is a bit of an unusual request. There may be better alternatives in some situations, but I don't want to add answers that would be irrelevant.

This is accomplished by setting the file permissions using the chmod command. In your case, you'll need to find the primary executable file for somepackage and run chmod og-rwx somepackage you'll probably want to set yourself as the owner so you can still use it with the following chown <your-user-name> somepackage. If it's owned by root, don't forget to sudo.
Updated per xenoid's comment to disallow anyone from copying the file and changing permissions on this file. tested on macOS 10.12.

Not enough.... someone could still copy the file elsewhere and change the execution flag of the copy. You must make the file unreadable as well.

chmod 640 /path/to/sompackage or /path/to/somefile ; sudo chmod +i /path/to/somepackage or /path/to/somefile ( the chmod +i enables the immutable bit once set as desired only someone in the packages' primary owner group would be able to change this, similar to a .lock file
