Yesterday pi-hole v6.0 was released, many changes and additions.

Updating the LXC with the update or pihole -up seems to break things. Updating using the first method at least makes the dashboard inaccessible, the latter throws an error in proxmox and the LXC is not bootable anymore.

whats your change? IPV6?

[pictosun]

I think it needs to be a rewrite of the script for Pi Hole overall. So many things changed.

i think not. Because the script do nothing 😄 the script simply execute the function of pihole himself.

Same function call like the official docu.

@MickLesk As far as I understand the config files are now at /etc/pihole/pihole.toml - That's new - and the cript does write into conf files. So maybe this is a point?

You also need to disable ntp in pihole config. This doesn't work with proxmox :

i know, i have this already so in my dev. im at testing...

[nicedevil007]

whats your change? IPV6?
I used a VLAN.
I thought my changes are visible from the log output.

Try it with adding unbound.

Okay fixed in my Dev Branch. I Test it and give an bash curl later, because i cannot Test completly without Change my infrastructure ^^

[MickLesk]

so, i have an tested script.. can anyone confirm? Especially with unbound?

bash -c "$(wget -qLO - https://github.com/MickLesk/Proxmox_DEV/raw/main/ct/pihole.sh)"

Now I just have to think about how I can migrate an existing installation. Apparently the biggest part (migration from .conf to .toml) is already done by PiHole itself.

@MickLesk : i tried your script, seems like it is almost working. but it is not seeing the unbound and still using googles dns.

DNSMASQ_WARN	Warning in dnsmasq core:

no upstream servers configured

[MickLesk]

Can you Test again? Pushed an commit 5min ago

[kilnake]

EDIT: I ran two scenarios, one with unbound and other without unbound. Both had same error listed below.

Same error : "no upstream servers configured"

&& was it meant to be changed "install unbound" default to no?

[MickLesk]

now you can test
