Experimental Debian (SID) Software Repository
for the PPC64 big endian architecture (64 bit only)

WARNING Our *experimental* repository is for PPC64 (PowerPC 64 bit) only (e.g. G5 based Apple Macs or QorIQ 64bit CPUs), and it will not work on 32 bit only CPUs, such as G3 or G4 based Apple Macs.
In order to install a 64 bit Debian SID, you may want to use the net installer CD unofficially provided by Debian
   http://cdimage.debian.org/cdimage/ports/current/ppc64/iso-cd/debian-10.0-ppc64-NETINST-1.iso
and use their PPC64 bit repository as the main source of software
   deb http://ftp.ports.debian.org/debian-ports/ sid main

1) add the gpg key related to the repository

sudo -s wget -O - https://repo.powerprogress.org/debian/conf/public.gpg.key|sudo -s apt-key add

2) edit the list of repositories checked by apt by adding it to the /etc/apt/sources.list

deb [arch=ppc64] https://repo.powerprogress.org/debian sid main

3) tell apt to prioritize the powerprogress repository (pinning priority) by editing the file /etc/apt/preferences (create the file if it doesn't exist) where you should add the following lines:

Package: * Pin: origin repo.powerprogress.org Pin-Priority: 1001

4) update the apt database

sudo apt-get update && upgrade

If it is the first time you added the repository, apt-secure must be invoked

sudo apt-get update --allow-releaseinfo-change

After all that, you may want to try installing Firefox from the newly added repository:

sudo apt install firefox
