Recently I needed to add an alias on my Mint 18.2
Since it is based on Ubuntu this should work for it to.
The /etc/modprobe.d/aliases does not exist and it is not used by OS if you create it.
If you need to add an alias just create a .conf file inside of /etc/modprobe
I added it to
/etc/modprobe.d/aliases.conf
Hope this will help.
