UPDATE 2025/06/21 – I’ve contacted the Pi-Hole package maintainer for Alpine Linux and it has now been fixed and updated to 6.2.3!
Please disregard everything else in this post
Quick PSA: I’ve just noticed Pi-Hole 6.2.2 crashing every 2-3 minutes on my Alpine Linux machine and the reason is that pihole-FTL is broken.
This is a super easy fix, just update pihole-FTL to 6.2.3 manually and you’re good to go.
Download it via https://ftl.pi-hole.net/v6.2.3/ and pick the appropriate architecture.
chmod +x it and move it to /usr/bin/
service pihole restart
Done.
You’re welcome.
