Newly imaged with Raspberry Pi imager

sudo apt update and upgrade went fine with about 8 updates.

Pi-hole install fails with

E: Unable to locate package idn2
E: Package 'jq' has no installation candidate
E: Package 'lighttpd' has no installation candidate
E: Package 'php-common' has no installation candidate
E: Package 'php-cgi' has no installation candidate
E: Package 'php-sqlite3' has no installation candidate
E: Package 'php-xml' has no installation candidate
E: Package 'php-intl' has no installation candidate
E: Package 'php-json' has no installation candidate

I'm using all the default settings for pi-hole installer.

nslookup raspbian.raspberrypi.org indicates everything looks fine.

I uncommented repositories in /etc/apt/sources.list and /etc/apt/sources.list.d/raspi.list then re-run sudo apt update

I've re-imaged twice with same result.
My router was just factory reset and doesn't do anything special yet.

What do these commands show?

lsb_release -a

uname -a

cat /etc/apt/sources.list.d/raspi.list

sudo apt update

What command or commands are you using to do the Pi-hole install?

lsb_release -a gives

No LSB modules are available.

For installing pi hole I followed
https://github.com/pi-hole/pi-hole/#one-step-automated-install
First trying
curl -sSL https://install.pi-hole.net | bash
than downloading and installing using

wget -O basic-install.sh https://install.pi-hole.net
sudo bash basic-install.sh

Used defaults for both installs, and both fail the same way.

Not sure if this is important, but:

n@pihole:/etc/apt $ apt-cache madison idn2
   libidn2 |    2.3.0-5 | http://raspbian.raspberrypi.org/raspbian bullseye/main Sources
 libidn2-0 |    2.0.2-5 | http://raspbian.raspberrypi.org/raspbian bullseye/main Sources
n@pihole:/etc/apt $ apt-cache showpkg idn2
N: Unable to locate package idn2

What do you see in /etc/apt/sources.list?

I uncommented the last line in both of these:
sources.list:

deb http://raspbian.raspberrypi.org/raspbian/ bullseye main contrib non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
deb-src http://raspbian.raspberrypi.org/raspbian/ bullseye main contrib non-free rpi

sources.list.d/raspi.list:

deb http://archive.raspberrypi.org/debian/ bullseye main
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
deb-src http://archive.raspberrypi.org/debian/ bullseye main

Looks like the expected values.

Note:

I uncommented the last line in both of these:

You only need to uncomment those lines (starting with deb-src) if you need to get the source code, to compile your own versions.

Can you try to install any of these packages manually?

What happens if you try: sudo apt install jq ?
or sudo apt install idn2 ?

(If you receive an error, post the complete output here)

Also post output for below pls:

sudo grep . -R /etc/apt/preferences.*

We observed APT pinning for the jq package before but dont have a definitive answer yet why:

Package jq is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'jq' has no installation candidate

 sudo apt install idn2

sudo grep . -R /etc/apt/preferences.* returns nothing. There are no files in /etc/apt/preferences.d/

UPDATE: did another apt update/upgrade and libexpat1-dev,rpi-eeprom and libexpat1 were upgraded. Tried installing idn2 manually and it worked.

Did sudo bash basic-install.sh and it the installation seems to have worked. Must have been something in one of those packages.
