Unable to install Pi-hole, "Unsupported OS Detected"

[Ibrahim_K]

Expected Behaviour:

According to the list of supported OS's on: https://docs.pi-hole.net/main/prerequisites/

I should be able to complete the installation without issues.

Hardware is a Raspberry Pi

Here is my info from running cat /etc/os-release

Actual Behaviour:

I get the following error: "Unsupported OS Detected"

I tried the following to no avail:
curl -sSL https://install.pi-hole.net | sudo bash
curl -sSL https://install.pi-hole.net | PIHOLE_SKIP_OS_CHECK=true sudo bash
curl -sSL https://install.pi-hole.net | export PIHOLE_SKIP_OS_CHECK=true sudo bash

All result in unsupported OS error.

Please help

What does dig -t txt versions.pi-hole.net show?

[DanSchaper]

And you can try curl -sSL https://install.pi-hole.net | PIHOLE_SKIP_OS_CHECK=true sudo bash -e as well.

This results in the same unsupported OS error.

[DanSchaper]

dig -t txt versions.pi-hole.net

You didn't use the right domain name that I asked for.

[Ibrahim_K]

oops, nice catch!

Here is the right one.

[DanSchaper]

You have no DNS servers available?

How are you even getting the installation script? dig install.pi-hole.net and dig google.com please.

[Ibrahim_K]

Both of these commands returned the same result as the versions one. "No servers could be reached"

I am connected to WiFi and a ping to google.com does work.

[DanSchaper]

I'm not really sure how that's possible?

Hi DanSchaper
I'm having the exact same issue when installing Pi-Hole (on Amazon-Linux).

The command you mentioned - doesn't work for me (neither adding PIHOLE_SKIP_OS_CHECK=true by export/set/just prompt before execution and few other ways that should have worked).

Do you maybe have another idea I can try?

BTW, this is my dig output (you will see redhat, but this is my manipulation only, I tried it without it and it didn't worked as well):

Thanks, and please tell me in case you prefer I will open a new post.

Amazon Linux is unsupported but you may be able to get around the check with:

curl -sSL https://install.pi-hole.net | PIHOLE_SKIP_OS_CHECK=true sudo -E bash

You are right, it did worked

Thanks Dan, really appreciate the quick response

I've legit spent the last 2 hours trying to find the right way to install this on my rpi 3B+ with raspbian stretch and this was the only one that worked thank you so much dan!

[Ibrahim_K]

This worked, guess i missed the capital -E the first time.

Thanks Dan!
