DietPi-Software | Pi-hole: Add version 5 support

[maartenlangeveld]

Just testing Pihole v5 (beta), in order to add domains (blacklist, whitelist) through pihole's web interface, user 'www-data' needs to be part of 'pihole' group.

Many thanks for your report. Yes indeed there is also some more testing and tweaking required/possible with v5. I'll do that the next days, the new pihole group is already good to know.

Hi Michael, With pleasure. Have also tested your new NanoPi NEO2 buster dietpi image but cannot get my NanoHatOLED working... Seems that I2C is not supported in the Buster build (works well with strech build). Is there a solution? Many thanks & kind regards, Maarten

Many thanks for testing. Could you please try to edit /boot/armbianEnv.txt and add:
i2c0 to the overlays line, so it should look like this:

overlays=usbhost1 usbhost2 i2c0

There is also an i2c1 overlay available, not sure which one uses which pins.
And if you don't use Docker, add the following as new line as well, which should lead to minor performance enhancements:

docker_optimizations=off

Jep many thanks. Will run some further tests the next days, I think there are more things that should be adjusted for Pi-hole v5 compatibility.

[MichaIng]

Done: b90b49f
Changelog: d5a44d0

@MichaIng
I guess it will impact new installation only? Right?
What about existing installation? Should we do anything on it as well?

[MichaIng]

@Joulinar
Good point. We can check on update if dietpi group exists and in case add www-data user to it.

[MichaIng]

Pi-hole v5 as well depends on PHP intl module now: c18f6c6

[MichaIng]

v5 compatibility guaranteed with next DietPi-Update: 9dc9596

I tested 2 scenario on my Buster VM

1. upgrade from v6.28 to v6.29 with an already existing PiHole installation
2. install new PiHole on v6.29

Both are working fine and PiHole 5 was working ootb after upgrade.

@Joulinar
That is great, many thanks for testing.

Tested upgrading from DietPi 6.28 to 6.29 on RaspberryPi B Rev 1. Only really running Pi-Hole 4 on this which I then switched to the Pi-Hole 5 Beta branch. All seems to be running okay so far.
