Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

I tried reconfiguring and adding repositories and anything i could, but that libgl1-mesa problem is still there.

Also, the real problem comes when i launch steam installer. Here is what happens:

Steam needs to install these additional packages:
libgl1-mesa-dri:i386, libgl1:i386, libc6:i386

Please do not use language like you did in your post, and which I have now removed.
This is a forum for users of all ages and our terms and conditions say clearly that profanities MUST not be used.

You are obviously frustrated by this problem but you are more likely to get useful answers if you state clearly the problem and give as much information as you can.

I am not a gamer and have not used, nor do I fully understand steam and its use and installation, but the dependency problems you ask about can be caused by having added PPA repos to your system; do you have any of those enabled?

[techtheguy]

oops. sorry. I think i have exagerated. I dont have an other PPA apart the default ones. Im sorry. Also, corrected the "human error" i did in the question. Added more useful info.. thansk

You've likely not done this bit:

sudo dpkg --add-architecture i386

Steam is 32-bit and needs a bunch of 32-bit libraries. If you don't say that it's OK to install 32-bit things, your package manager won't.

After performing a minimal install of 20.04.1 LTS, I tried:

apt install steam

and got the following error:

The following packages have unmet dependencies:
       steam:i386 : Depends: libudev1:i386 but it is not going to be installed

I noticed that focal-updates was not in my sources.list so I ran:

sudo apt-add-repository "deb http://archive.canonical.com/ubuntu $(lsb_release -cs)-updates main restricted universe multiverse"

And after this,

apt install steam

worked.
