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 ... _ppc64.deb
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

Good to know. Thank you.

Do you mean a screenshot utility? I use gnome-screenshot on MintPPC32.

I mean Debian snapshots https://snapshot.debian.org/archive/deb ... 0T014110Z/.
I am used them in apt/sources.list instead of plain unstable. Because unstable has very often broken packages dependencies, for me is better to point at some exact snapshot and have my main working linux fixed here.

Is this Mint install base? As I see some Mint repos in your sources list. I gave on up Mint because some packages are broken and have some kind of Clang error. For example Zenity won't work. Gives some kind of relocation error associated to Clang or something similar.

OTOH Debian Sid works well enough. I have no major issues and it works quite well and stable. But, almost opposite to Linux PPC in general, there's too many updates! However, my system lacks a history buffer in terminals, as it's wiped on every boot. I don't know why, as my terminal settings have it activated, so I kinda gave up on using it more as annoying things not working are not worth my time trying to fix.

Lately I've been spending more time testing kernels which can be time consuming enough and more so if I test it across different installs I have.

No, it is Debian Sid. Mint in sources.list is only for Mesa downgrade.

Do you have in sources.list unstable ?
I had unstable there some time, but I often ended with broken packages or non-working apps like Libre office or Gimp.
Now I am using instead of directly unstable some exact snapshot. Mostly that one where JP Adrian Glaubitz made installation snapshot.

Okay, I have both Debian and Mint installed, but only Mint has those Mint sources. I applied the apt pin to hold back Mesa but don't recall where now. Would be on here somewhere.

Yes I do. I realised after rereading my post it would have been beneficial to post my Debian sources.list. So here it is. Apt also keeps telling me about converting it to a modern list. But, I tried that once, and it broke my sources, so I went back to a classic list.

Thanks! I will try and look if something will be broken.

in this snapshot not works Gimp and some minor things, others works
Mintppc repo is for downgrade mesa
