[Solved] x86 Ubuntu install trouble / dependencies

YFZdude

Pi Model or other hardware: x86
RetroPie Version Used: 4.7.15
Built From: Manual install over Ubuntu 20.04.2

Here is what I did (the second attempt this is...)

-Install Ubuntu 20.04.2
-choose minimal install, tick box for third party drivers
-sudo apt update && upgrade
-sudo apt install -y git dialog unzip xmlstarlet
-git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.git
-sudo RetroPie-Setup/retropie_setup.sh

Then I receive the error:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 build-essential : Depends: libc6-dev but it is not going to be installed or
                            libc-dev
 g++ : Depends: g++-9 (>= 9.3.0-3~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Unable to install packages required by /home/jack/RetroPie-Setup/retropie_packages.sh - Could not install package(s): subversion curl gcc g++ build-essential python3-pyudev.

So I type:
sudo apt install libc6-dev

and receive:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libc6-dev : Depends: libc6 (= 2.31-0ubuntu9) but 2.31-0ubuntu9.2 is to be installed
E: Unable to correct problems, you have held broken packages.

So I am determined to get the right package version, type:
sudo apt install libc6=2.31-0ubuntu9

This downgrades the package and I can now run the Setup script. So run the script and choose to manage packages and install all core packages.

This fails to install emulationstation or retroarch. Here is snippet of log:

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

 libpulse-dev : Depends: libpulse0 (= 1:13.99.1-1ubuntu3.8) but 1:13.99.1-1ubuntu3.10 is to be installed
                Depends: libpulse-mainloop-glib0 (= 1:13.99.1-1ubuntu3.8) but 1:13.99.1-1ubuntu3.10 is to be installed

               Depends: libglu1-mesa-dev but it is not going to be installed

 libudev-dev : Depends: libudev1 (= 245.4-4ubuntu3) but 245.4-4ubuntu3.4 is to be installed
E: Unable to correct problems, you have held broken packages.

Last time this happened (1st attempt on a normal install type) I downgraded libasound2-data to the expected version and in the process it removed my desktop environment. I didn't figure that out until after installing the rest of RetroPie and rebooting.

Here is what apt says about libasound2-data downgrade:

 sudo apt install libasound2-data=1.2.2-2.1

Do you want to continue? [Y/n]

EDIT: So my question is what happened, and do I need to wait for an update to package dependencies information or is this result and the manual re-install of the desktop environment the way to go?
I've done manual install before on this type of PC and didn't have trouble like this back then.

This looks like the relevant error. Do you have any held packages ? Any 3rd party repos ?

@mitu
I'm not sure how to tell if I do. Is there a way to list them out? I didn't edit the sources file for apt. It should be the stock file.

This is from a clean OS install with no extra steps between first boot up and running the RetroPie manual install process as written on the Docs page. The only thing you might call unusual is that I declined to connect to a network during the OS install and I manually connected and updated after logging in the first time.

If you think it might be caused by the Ubuntu repositories, I could try a clean install and skipping the sudo apt upgrade prior to the setup script install.

You could change your current Ubuntu repository mirror and retry (apt update first). You can use apt-cache policy to check the troublesome packages and see what version are available and from which repository.

I was unable to find held packages, but you got me going in the right direction. For whatever reason, my sources.list file had a comment in it that suggested that because I used a smaller ISO it might not have been the full file. Perhaps a side effect of not allowing online updates during install.

So I got hold of a more 'full' listing of the official sources and ran apt update and it suddenly had way more packages to update and then the install script could find more of what it needed.

Thanks!
