Pihole refuses to update on Trixie

[fhals]

Hi all,

after upgrading from bookworm to trixie, pihole refuses to update.

pihole -up
[✗] Unsupported OS detected: Debian 13

The running pihole-instance reports: Core v6.0.6, FTL v6.1, Web interface v6.1

Is there anybody, who already worked this out?

G_DIETPI_VERSION_CORE=9
G_DIETPI_VERSION_SUB=20
G_DIETPI_VERSION_RC=1
G_GITBRANCH=‘master’
G_GITOWNER=‘MichaIng’
Linux space 6.12.57+deb13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.57-1 (2025-11-05) x86_64 GNU/Linux

Thanks for help, Frans

Try this

PIHOLE_SKIP_OS_CHECK=true pihole -up

Thank you, ignoring the problem led to a successful update

My guess is that you are running a pretty old installation of pihole. The OS check was removed with version 6 and when version < 6 was current, Debian trixie was not released yet, so it was “unsupported”.

See https://discourse.pi-hole.net/t/unsupported-os-detected-debian-12/81101

Maybe we can ask the Pi-hole team to update the versions.pi-hole.net TXT record one more time, to make updates for Pi-hole v5 users easier.

According the first post, it was already Pihole 6.0.6

… then whichever v6 subversion the OS check was removed .

Now I see the record was even removed in between but readded, just not updated.
