Error Installing Steam Dependencies

I recently beansed my computer by installing a package while neglecting to note that it would remove a significant portion of the OS (Ubuntu 22.04.2 LTS). While I’ve reverted much of the damage caused by this error, I am running in to a problem when attempting to launch Steam. It tries to install dependencies but proceeds as follows:

Steam needs to install these additional packages:
libc6:amd64 libc6:i386 libegl1:amd64 libegl1:i386 libgbm1:amd64 libgbm1:i386 libgl1-mesa-dri:amd64 libgl1-mesa-dri:i386 libgl1:amd64 libgl1:i386 steam-libs-i386:i386

Press return to proceed with the installation: 
.........W: https://hub.unity3d.com/linux/repos/deb/dists/stable/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

E: Unable to correct problems, you have held broken packages.

Notably (or maybe not) libglx or a related package is the package I remember installing that beansed the computer in the first place. I was rather cavalierly trying to resolve “broken packages” issues in a quest to fix another application. Also, I am not sure why the reference to Unity3D appears in the first few lines- could that be a problem? Thanks!

Edit: I’ve tried manually installing the dependencies listed but they all apparently ultimately depend on libglapi-mesa:i386, which wants me to uninstall essential system components and repeat the beansining I just tried to revert… I’ve tried various methods to resolve the “held broken packages” but no dice so far.

I encountered an almost identical problem on my system, and I fixed it by purging the oibaf PPA:

sudo ppa-purge ppa:oibaf/graphics-drivers

You'll need to install ppa-purge if it's not already installed.

I see "oibaf" in the version numbers in your logs above, so it appears you added this PPA at some point and are using packages from it. I suspect some conflict between that PPA and Ubuntu standard packages cropped up at some point recently.
