I already upgraded my rasbian to bullseye. When i try to upgrade "core" to beta v5.4, this is the output:
root@raspberrypi2:~# pihole checkout core release/v5.4
Please note that changing branches severely alters your Pi-hole subsystems
Features that work on the master branch, may not on a development branch

https://docs.pi-hole.net/main/prerequesites/#supported-operating-systems 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 | PIHOLE_SKIP_OS_CHECK=true sudo -E bash If you are seeing this message after having run pihole -up: PIHOLE_SKIP_OS_CHECK=true sudo -E 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: https://discourse.pi-hole.net/c/bugs-problems-issues/community-help/
