Error: Unable to update package cache. Please try "\e[1;31m"root
Installing on machine with nextcloud.

[jfb]

What installer or command were you running that generated this error?

[smokingwheels]

https://github.com/pi-hole/pi-hole/#curl--ssl-httpsinstallpi-holenet--bash this site.
Just a copy and paste to a Bitvise SSH terminal window.

The curl -sSL https://install.pi-hole.net | bash
There is ’ ’ around the command line
copied from git hub

curl -sSL https://install.pi-hole.net | bash

There is 4 x # at the start of the the command

I think I see the problem 2 different results from the web page?

[DanSchaper]

If there’s a problem with the package cache then sudo apt update is failing to run. Try that command manually.

[smokingwheels]

I did apt clean then the install bash command and it still fails.
I have the same error on ubuntu a 2nd pc.

[DanSchaper]

What is the output from sudo apt update?

[smokingwheels]

Lots of errors
Idea Do we need a Whitelist of all the Linux sources so we dont block them?

They aren’t blocked, you just don’t have the GPG keys for the packages signed by those repositories. That’s not something that Pi-hole would have any control over.

[DanSchaper]

Not to mention you have Stretch, Disco, and Cosmic repositories which is just a recipe for system implosion.

[smokingwheels]

I know they should not be there.
Not sure whats going on.

[jfb]

It may be time for a clean system reinstall.

[smokingwheels]

I have Lots of Marie’s Wagnwash data no free space to backup.
She wont backup all the work I have done to allow a fresh install.

[deHakkelaar]

wget the proper GPG keys from the repos that have key problems and add them for quick fix eg for https://packages.sury.org/php :

cd ~

wget https://packages.sury.org/php/apt.gpg

sudo apt-key add - < apt.gpg

EDIT: Forgot to mention, you got to trust these guys not to do harm by adding their key!
