Maybe just read the post before typing a reply? I already said Steam says not to install with Snap or flatpack because of issues it causes with SteamVR.

I just did a fresh install of 24.04 the other week.

this is definitely what you need. Here is what I have installed.

this error
sounds like a UI app store or the software updater is currently running, or more likely, was running and never released it's lock. I've had that occasionally happen to me in the passed (maybe hand full of times in 20 years). Usually, I try close every application, reboot, apt update and apt upgrade and if all that fails to reset the lock files situation, I just delete the lock files, but that can also corrupt the package managers DB. See here[wiki.debian.org]
Which recommends
As a last resort, kill the frontend lock file. I mean, what else can you do? You can read some discussion about it here[askubuntu.com] It's the second answer you want to read with 955 upvotes.

-----------------------------------
As suggested in your github discussion here[github.com]
download the .deb file and then
But I think you will still run into the lock file issue.

If the excellent advice from HighBall is too much for you, and you can't do it. You want to give up (however, I encourage you to try it).
You can try pop-os (graphics driver included), mint, manjaro there it will be easier. The Steam package will be included in the distribution.

You can get help with commands by typing in the console: man the name of the command.
man dpkg

Shutting down the console ends all its processes, it's a bad idea to close it when you're in the middle of doing something from the root (sudo) account.
Here it works a little differently than in windows, the ending with a cross is quite brutal.

Ok I'm reading, your git hub help thread.
I understand what is going on, you are in a big shock and you do not understand what is happening. Just read what the programs write to you, read carefully and with concentration. In linux, the program doesn't write nonsense to you, it's all important things and helpful tips. If you had read and followed the suggested tips, in the first attempt, you would not have had a problem. But you closed the window halfway and locked the packet database.

sudo dpkg --configure -a
The advice apt gave you is what you should do first.
As you can read in man dpkg, this will finish configuring the packages you left off and unlock the apt database.

Kisak-Valve has given you a good factual answer, hats off to him.
I didn't think that in valve help you can get such a good answer about linux.
Unfortunately, a bit too complicated for you ;P


Hey, it's simple, do it slowly and carefully.
In principle, always using root privileges your steps should be in the utmost caution.
In linux as root, nothing will ask you if you are sure. The commands will simply be executed if possible.


Slowly, calmly, forward

edit:
sudo dpkg --configure --pending
sudo dpkg --configure -a
it's the same command typed in two different ways

DO NOT USE FLATPAK!!!!!!!!!!!!!!!!!!!!!!!!!
for ubuntu:

sudo add-apt-repository multiverse
sudo apt update
sudo apt upgrade
sudo apt install steam

Okay, read through these and got it working! Thanks. Passed around some Steam points for helping explain this.

I don't want to be rude, but it seems that the best answer came from Differson Midly. Of all of us, he probably knows ubuntu the best.

Information I used to find out what a multiverse repository is:
https://askubuntu.com/questions/89096/how-do-i-enable-the-multiverse-repository#553847

I manually went to the archive:
http://us.archive.ubuntu.com/ubuntu/pool/multiverse/s/steam/

Direct path to the valve repository for the curious:
http://repo.steampowered.com/steam/pool/steam/s/steam/


If you downloaded steam from the valve website, you should definitely add this multiverse repository. You can do it right now, nothing will break.
(You can execute all 4 command lines)
