@mitu thanks for the info I didn't know there was one for windows similar to this will check it out

@StarshipKnight That's a generic error message when the compilation (and the follow-up installation) fails. You'll find the detailed error message in the ~/RetroPie-Setup/logs folder, in the most recent log file.

@mitu for sure

Hello @johnodon, good morning, how are you? Dear, please ask a question regarding the installation:

I have a small problem with my installation.
I use the Ubuntu server, running on a notebook with a processor:
Intel(R) Core(TM) i3-2350M CPU at 2.30 GHz
After following the step-by-step configuration, I have detected this error when booting the system:

"Last login: Monday, December 4 03:37:51 2023
There is no such key “default-show-menubar”
There is no such key “default-show-menubar”

My version of Ubuntu is

Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
I emphasize that when the system starts, the control image appears in the shape of a cupcake, then the error appears.
What can this be?
thanks
