Thread necro, but same problem, and a way to resolve...

Get into the command prompt go to the ~/RetroPie-Setup/scriptmodules/supplementary directory Delete the old retropie-manager.sh file Download the correct script from the github repo (https://raw.githubusercontent.com/RetroPie/RetroPie-Setup/master/scriptmodules/supplementary/retropie-manager.sh) Go back to RetroPie setup again and now the script should work and install retropie-manager.

("code" is below if needed)

F4 cd ~/RetroPie-Setup/scriptmodules/supplementary rm -r retropie-manager.sh wget https://raw.githubusercontent.com/RetroPie/RetroPie-Setup/master/scriptmodules/supplementary/retropie-manager.sh

My first instinct was to ask you to check if you're connected to the internet, but you said you updated so I figured out you don't have this problem.
Glad you figured it out.

@tylerx Retropie Manager is an unofficial addon and people seem to be having many issues with it. I have used it though - did you follow this?
Also,

Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

which you agreed to do.

I dont know much about diagnostics or what is technically considered "free" I suppose people define it differently.

It seems there is no shortage of raspberry pi dashboard projects:

Wow thanks! I could have sworn I'd removed and added again. but this process worked. Cheers!!
