Arch Linux User Repository

ArchLinux Pi-hole is not officially supported by Pi-hole project. In case of bugs and malfunctions please DO NOT file a report upstream.

First of all check if the wiki (https://wiki.archlinux.org/index.php/Pi-hole) can help then ask here for assistance and tips.
When it will be excluded that the problem does not depend on ArchLinux we will file a bug upstream.

to update to pi-hole 6, please use pi-hole-core pi-hole-ftl and pi-hole-web packages.

oops, sorry

@max.bra do you forget the first part of the patch? (systemctl stop)

@disprofarma done, thanks for reporting

Hi @max.bra, the file /opt/pihole/piholeARPTable.sh ("pihole arpflush" command) needs a tweak to work:

Likely your problem. Build the three packages with makepkg and install them with pacman. AUR helpers rarely help.

Could you clarify what AUR helpers are doing that would cause issues and be different from just makepkg -si? I don't really run into issues with AUR helpers, besides maybe having to clean-build every once in a blue moon.

Also, unfortunately, installing the 3 packages that way did not fix the problem in my specific case. Any other ideas?

all update status management is handled through the /etc/pihole/versions file

$ ls -l /etc/pihole/
....

$ cat /etc/pihole/versions

during installation, upgrade and from time to time is runned

sudo -u pihole bash /opt/pihole/updatecheck.sh

i am firmly convinced that for some reason your /etc/pihole/versions file is not being updated. it cannot be otherwise.

@max.bra - even though 6.0.5-1 is installed, the footer of web GUI reports:

Core 6.0.4FTL v6.0.4Web interface 6.0.1

I updated the system via the paru aur helper,

Likely your problem. Build the three packages with makepkg and install them with pacman. AUR helpers rarely help.

Following a system update, pihole is yet again not working.... Every other package on my server has almost 0 issues starting up again after updates, but this one rarely wants to. Anyway....

Following the update to v6, I still had pi-hole-server installed instead of pi-hole-core for whatever reason. I updated the system via the paru aur helper, and looking at the logs, I see pi-hole-web-6.0.1-1 and pi-hole-ftl-6.0.3-1 were both installed/updated, but nothing else pi-hole related. Once I realized this, I installed pi-hole-core 6.0.4-1 (which correctly uninstalled pi-hole-server) and restarted pihole-FTL.service.

Even after this, I'm still not getting DNS resolution from client devices, but I see the config options in /etc/pihole/pihole.toml don't match what I had previously in /etc/pihole/pihole-FTL.conf. Frustrating but no biggie, I'm working on getting those updated. In the meantime, I've noticed some strange errors related to the pihole command:

$USER@$HOST ~> pihole status
/usr/local/bin/pihole: line 306: getFTLAPIPort: command not found

/usr/local/bin/pihole: line 306: getFTLAPIPort: command not found

Core version is 6.0.4 (Latest: v6.0.4)
Web version is 6.0.1 (Latest: v6.0.1)
FTL version is v6.0.3 (Latest: v6.0.3)

This is despite the systemd service running and not reporting any obvious errors. Is there something I'm missing? I also tried following the commands on the arch wiki but had similar trouble:

$USER@$HOST ~> pihole -a setdns 127.0.0.1#53
/usr/local/bin/pihole: line 28: /opt/pihole/webpage.sh: No such file or directory

@graysky here i am

Web version is 6.0.1 (Latest: v6.0.1)
FTL version is v6.0.2 (Latest: v6.0.2)
