DietPi-Software | Pi-hole: Allow install without web UI

[Trunkzeh]

Creating a bug report/issue

Required Information

• DietPi version | 7.0.2
• SBC model | RPIZero-W
• Power supply used | Anker Multi-5port unit
• SDcard used | Sandisk Ultra

Additional Information (if applicable)

• Software title | (PiHole)
• Fresh software install
• Can this issue be replicated on a fresh installation of DietPi? Yes.
• Bug report ID | 7b1d1bf6-6730-423f-9ae8-951befe289f0

Steps to reproduce

1. Select PiHole install within dietpi-software; when prompted to install unbound select No / cancel.
2. Part of the PiHole install will ask if you want to enable web-gui; select No.
3. DietPi will install PHP & webserver files nonetheless in this instance; incorrect behaviour?
4. Continue installation process; past if you want to enable / disable public page.
5. Installation will fail on this step:

[FAILED] DietPi-Software | cd /var/www/html/admin

Expected behaviour

1. PiHole should install without PHP and webserver components.

• ...

Actual behaviour

• See above.

Extra details

Looks like the script is looking for the webgui html files in /var/www/html/admin which naturally are not there as pihole has installed without a webgui.

Many thanks for your report.

Indeed we expect the web UI to be installed, and I guess >99% if users do it anyway. But I agree it would be great to allow a lightweight install without web UI.

It's a larger task since it requires a different way of how dependencies are resolved. Currently the webserver and PHP are installed before the Pi-hole installer is called. When switching it, we need to test if the Pi-hole installed runs through successfully when installing the web interface without having a webserver installed already (and skipping the included Lighttpd install).

You are right - normally i would install the webgui; however im trying to run as lightweight as possible on the rpi zero as its not exactly fast; the zero acts as my backup dns instance incase the rpi4 goes down for whatever reason; that naturally has pihole webgui. I'm going to re-image the zero again and then install via the default pihole install script (rather than dietpi) and feedback :)

[MichaIng]

Jep, I see the use cases.

re-image the zero again and then install via the default pihole install script

No need to re-image. pihole -r > Reconfigure and uninstalling webserver + PHP via dietpi-software would do it as well 😉.

[Trunkzeh]

I thought of doing that; however the webserver package(s) dont show up on the uninstall menu of dietpi-software in the above scenario. I'm not sure because the script hasnt registered the installation when it was initially running the original pihole job if that makes sense? Only having a logical guess.. I havent the faintest clue on the mechanics of dietpi's optimized software scripts.

Edit - I should note; they DO when attempting to uninstall on a successful pihole install; i've confirmed this previously on my rpi4. But not on the pizero which has had the pihole job fail due to the above webserver issue.

[MichaIng]

Ah yes that makes sense when the install didn't went through. We need add a pending state for installs which allow another install as well as an uninstall 💡.

[Trunkzeh]

Personally; this ticket can be closed. I was able to install pihole via the developer's standard installation procedure (their install script) and have it operate without a webgui with no extra steps. 99% of everybody installing pihole would utilize a webgui and dietpi works out of the box :-)

TLDR; pihole works great on dietpi. If you want to run it without a webgui; install using the official pihole installation script rather than from dietpi-software.

[MichaIng]

Let me keep it open, as I find it reasonable to allow an install without web UI via dietpi-software as well.

Any update on this? I just try to install pi-hole thru dietpi-software, and it force me to pre-install a web server and PHP. Of course the pi-hole install script still allow to skip web interface, so I have to uninstall the web server and PHP manually.

[Joulinar]

currently there is no plan to offer such an install option without web interface.

[thanhminhmr]

I don't think there is a need to support that use-case. Just show the user that: dietpi-software doesn't support no web interface install, and if the user want that then please use the install script directly from pi-hole. Something to inform user would be nice.
