To fix this issue, simply open the install_linux.sh script shipped with the installer in a text editor and change Line #205 from this:

pkg=”mongodb-org-server_$mongoDBVersion_amd64.deb”

to the following which now contains brackets “{ }”:

pkg="mongodb-org-server_${mongoDBVersion}_amd64.deb"

Save install_linux.sh and re-run it to complete the installation.
