the list of sources could not be read

[mitu]

You've modified the apt source list and it doesn't find the package. Add to the list

deb http://raspbian.raspberrypi.org/raspbian/ stretch main contrib non-free rpi

and the re-run apt update before re-trying the install.

[asianchinaboi]

@mitu how do you add that to the list

[mitu]

@asianchinaboi Edit the file and add the line at the end, similar to how you fixed the broken file in the first place.

[asianchinaboi]

@mitu Is the file supposed to be a folder?

[mitu]

@asianchinaboi No, it a text format file - how exactly did you fix the first error ?

You can use the nanoe text editor from the command line (exit EmulationStation first and plug in a keyboard) and edit the file, adding a line at the end with the contents I posted earlier

sudo nano /etc/apt/sources.list

@mitu
Did not find needed dependencies: python3-pyudev. Trying to install them now.

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
chromium-browser-l10n : Depends: chromium-browser (>= 72.0.3626.121-0+rpt3) but 56.0.2924.84-0ubuntu0.14.04.1.1011 is to be installed
python3-pyudev : Depends: python3-six but it is not going to be installed
rpi-chromium-mods : Depends: chromium-browser (>= 65) but 56.0.2924.84-0ubuntu0.14.04.1.1011 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
Unable to install packages required by /home/pi/RetroPie-Setup/retropie_packages.sh - Could not install package(s): python3-pyudev.

[mitu]

I think your APT configuration is pretty broken at this point. How did you end up with this configuration ? I'd advise you to re-install.

[asianchinaboi]

@mitu I installed a new retropie script from retropie setup

[mitu]

You said:

Built From:SD image on retropie website

but those entries you have in the apt sources (and other packages you might have installed) are not from the RetroPie image - you probably added them yourself in order to install something else (?). Furthermore, you seem to have added i386 as an architecture on the system, to what purpose I don't know.

Fix your apt, the errors you get are not caused by RetroPie or its configuration.

[muldjord]

@asianchinaboi Are you perhaps doing this on Ubuntu 20.04? I seem to recall reading that it has either removed or renamed that package python3-pyudev.

[mitu]

@muldjord Actually it was the other way around :) The python-pyudev package doesn't exist anymore (in Ubuntu 20.04), being transitioned topython3-pyudev now.

However, that's not the case here, since @asianchinaboi seems to have a Raspbian Stretch installation - according to both their account (SD image from RetroPie) and the contents of the apt sources list.

[asianchinaboi]

@mitu could you send me a image of what /etc/apt is supposed to look like?

[mitu]

My sources.list contains only the line I posted.
/etc/apt/sources.list:

deb http://raspbian.raspberrypi.org/raspbian/ stretch main contrib non-free rpi

In addition to that, there is also /etc/apt/sources.list.d/raspi.list with:

deb http://archive.raspberrypi.org/debian/ stretch main ui

[asianchinaboi]

@mitu thanks i ended up fixing it by doing
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

[asianchinaboi]

@asianchinaboi I also got rid of i386
