How can I restore Pi-hole's default ad lists?


The default ad lists are stored locally in /etc/.pihole/, so you can just delete your existing list and then copy the default one back into place.

rm /etc/pihole/adlists.list
cp /etc/.pihole/adlists.default /etc/pihole/adlists.list

Then, update the gravity ad list using pihole -g or updating the ad lists via the Web interface.

Another alternative is to remove the /etc/pihole/adlists.list and then run pihole -r, which will also accomplish the same thing by repairing your entire installation.

Note: Depending on what version you are on, you may have a /etc/pihole/adlists.default, which is being deprecated for /etc/pihole/adlists.list.
