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.

I also tried upgrading from pi-hole-server and when trying to manually pacman -U pi-hole-web after makepkg I get:

error: failed to commit transaction (conflicting files) pi-hole-web: /var/www exists in filesystem

@jeliebig hello jeliebig.

you should make sure that you have all three packages already built at the same time:
after downloading and unpacking the three snapshots, check if you are missing any dependencies that are not part of the three pi-hole packages and install them with pacman with the --asdeps option.
create the pi-hole packages (with the -d option on ftl and core) and move the three resulting packages to the same folder.

all that remains is to do a

pacman -U pi-hole-core-* pi-hole-ftl-* pi-hole-web-*

considering that you've already done even partial operations anyway maybe you'd better remove all the packages (keeping and managing the files in /etc/pihole) and install all over again, at this point also using an aur helper starting with just pi-hole-core

@all upgrade using pi-hole-core, or better make three package by NOT using an AUR helper for one time and install them at same time: "sudo pacman -U pi-hole-core... pi-hole-ftl... pi-hole-web..."

Not sure if I'm doing something wrong, but that doesn't seem to be possible. I previously used pi-hole-server and now want to upgrade using pi-hole-core.

Errors occurred, no packages were upgraded.

How am I supposed to do this properly? Also could the wiki page get a section to describe the upgrade process from v5 to v6?

Yeah beware with the new v6 pihole, they changed all the config files to the pihole.toml with a different format, the setupVars file does nothing now. I also didn't realise it now uses it's own webserver on port 8080, for some reason I still had the old webui on my Apache server I was using, that confused me for a while.

@df8oe happy you solved and thanks, appreciated.

Nice work to bring this to Arch - many thanks! After reconfiguring port 80 in /etc/pihole.toml everything is running fine now.

@df8oe admin web interface is now served by FTL with an internal web server

https://docs.pi-hole.net/ftldns/configfile/

lighthttpd (or any other webserver) is needed for many other applications that are running on this rpi... What webserver does pihole use now? There is no other webserver installed by the three packages...

@df8oe lighttpd is no more needed. you can disable and uninstall it

@all the use of --overwrite is not necessary and is dangerous too

@all upgrade using pi-hole-core, or better make three package by NOT using an AUR helper for one time and install them at same time: "sudo pacman -U pi-hole-core... pi-hole-ftl... pi-hole-web..."

Simple installation does not work for me. I have installed all three packages (some with --overwrite "*") and pihole-FTL service is up and running. But web interface is not accessible. If I try to access the .lp-files are offered for download. I think there is some lighttpd-configuration missing...
