[✗] Unsupported OS detected: Raspbian 12
If you are seeing this message and you do have a supported OS, please contact support.
If you wish to attempt to continue anyway, you can try one of the following commands to skip this check:
e.g: If you are seeing this message on a fresh install, you can run:
curl -sSL https://install.pi-hole.net | sudo PIHOLE_SKIP_OS_CHECK=true bash
If you are seeing this message after having run pihole -up:
sudo PIHOLE_SKIP_OS_CHECK=true pihole -r
(In this case, your previous run of pihole -up will have already updated the local repository)
It is possible that the installation will still fail at this stage due to an unsupported configuration.
If that is the case, you can feel free to ask the community on Discourse with the Community Help category:
