Okay I finally was able to install & boot with a older jessie install.
Upgrade to sid went fine, but now I cant install any GUI I like.
"apt-get install xfce4" error: Depends: xfdesktop4 (>= 4.12.0) but it is not going to be installed
"apt-get install xfdesktop4" error: Depends: libthunarx-2-0 (>= 1.1.0) but it is not going to be installed
"apt-get install libthunarx-2-0" error: Package is missing
Debian sid has no package for libthunarx-2-0, there is only libthunarx-3-0
When I try install Cinnamon, i get similar results, some depends are not build for debian sid powerpc.
How is it possible to install a GUI? I just tried follow ppcluddite debian guide.
I just built my DE from Openbox and had to use some workarounds to get the results I wanted, like installing Midori from Jessie-Backports (always dangerous, but it worked) and using old versions of fwcutter and b43-installer. I spent a lot of time enabling and then disabling older repositories to get the things I wanted. Other stuff, I just compiled on my own or scuffled around for downloads.
They're still filling out the repository, so there are things missing and others being updated. Such is the life of using an unstable repository. gvfs is currently broken due to gvfs-common being updated (and nothing else), so mounting drives and connecting to networks via any file manager doesn't work in the traditional sense at the moment. Luckily, I had installed the older version before the update, as trying to compile and install it on a second testing machine led to dependency hell. I haven't bothered to check incoming, so there's one possibility if you know what you're doing.
I know that budgie-desktop is fully available, if you don't mind a fork of Gnome 2. It's complete and has a macOS-like side panel notification plugin (Raven), so that could be fun to mess with. Info here-

As an aside, I've been checking for updates at least 2-3 times a day. I'm attempting to get Clementine to play... well... anything, as the required gstreamer plugins are missing, and there's a slim possibility that one could get the Spotify plugin to work and connect to their servers. The program does install, and I was able to get the Subsonic plugin to work and connect to my server, but no music will play due to the missing plugins. This is my current mission...
Here's a screenshot of my setup. Deepin was influential on how I setup and themed the DE, and the Deepin icon theme is actually available in sid unstable. I compiled an old version of Slingscold (a HUGE pain in the ass, but it worked in the end) for a Launchpad-like launcher and Skippy-XD for an Expose-like window switcher. Logout just uses obsession, which is built in to Openbox. I also modified a macOS theme for Openbox to use the flat traffic lights, but I'm a bit tired of those, so I used the Adwaita Revisited Dark OB theme with the Macterial window theme instead. Tint2 panel is there as well, but is hidden in the upper-right corner until toggled and only shows indicators for network, sound, Synapse, and notifications. Conky is an older version that I compiled to use my simple script (modified from ppcluddite's original script), as I can't get it to work with the new Conky lua syntax, and learning the new syntax is like watching paint dry:
