Debian Buster/Sid PPC64

[xeno74]

I've got SeaLion working on my Debian 64!

I needed the libffi6 package. I didn't need the libjpeg8 package but I located it just in case. I've found a snapshot for both PPC32 and PPC64.

FFI6:
https://snapshot.debian.org/archive/deb ... _ppc64.deb
https://snapshot.debian.org/archive/deb ... owerpc.deb

JPEG8:

https://snapshot.debian.org/archive/deb ... owerpc.deb

Thank you for the links and for testing SeaLion.

Yesterday I upgraded my Debian Sid Bookworm installation to Debian Sid/forky ( snapshot from 2025-08-21 19:45 ).
After installation xserver not started:

I "solved" this with renaming /usr/lib/xorg/modules/libglamoregl.so, now I can log to desktop, but without 2D acceleration. Do somebody know, how to fix it?
Maybe this Mesa fix will work? viewtopic.php?p=60770#p60770

Mesa fix works on ppc-64 with little changes:
apt-mark hold instead of apt hold and problem with keys --allow-unauthenticated --allow-insecure-repositories

Unfortunatelly, in my snapshot are broken gimp so I have to find snapshot where it works...
Did somebody know, which snapshot is best to use? I.e. with minimum broken packages.
I am used mainly Libre Office and Gimp
