Pi4, Pixel Desktop, 4K TV -- no go

@mitu Yes, I did that. All packages updaated.

Note, when installing the Pixel desktop, there are a number of

dpkg-deb: subprocess paste was killed by signal (Broken pipe)

errors - all stating that a file was used by another module.

mitu

@aaciii Looks like the installation did not complete correctly. Can you post the installation log - it should be in $HOME/RetroPie-Setup/logs - on pastebin.com ?

aaciii

Here it is. Seems like it wants to install a lot of libraries that are already installed (by what, I have no idea)

You didn't seem to have updated the OS or the kernel, the error log shows some dependencies are not available/not-installable, either an out-of-date apt repository cache or pinned packages (?).

Make sure you're fully updated when trying the installation

sudo apt -y update
sudo apt -y full-upgrade
sudo reboot

aaciii

I did do so -- there was this one module blocking installs. "xkb-data"

See this log I took of trying to fix dependencies with the command "apt --fix-broken install":

https://pastebin.com/N3jdPkBu

you'll see there is a conflict over and over with xkb-data 2.26-2

I forced dpkg overwrites on, and all is well now -- but I'd like to understand what that xkb-data module is and why it's in the way

Your kernel version shows you didn't update fully.

I don't see why that happens, I get no conflicts using the latest version from apt:

EDIT: can you run

apt-cache policy xkb-data

and post the output

aaciii

The same module blocks the apt full-upgrade process:

Here's the policy for that xkb-data module:

apt-cache output is ok, but the upgrade status it's wierd. Are you sure you've used the RetroPie image from retropie.org.uk/download and didn't modify any of the dpkg/apt settings (extra repositories ?) ?

aaciii

Totally sure, the only place I’ve ever gotten an image from is the RetroPie site. I have never messed with any command line update settings, and until this issue I have only updated using the RetroPie menu script.

aaciii

The only other package I ever installed is the rpie-art script package which is installed via command line (via git)

This is the process I followed for that. I don’t see how this could be related but just in case.

No, it's not related. Alas, I don't have any ideas - try using aptitude instead of apt, it's worth a shot.
