Steam crashes with no error message after updating to 20.04

Since upgrading to 20.04 from 19.10, Steam does not launch. I have tried installing via steam, steam-installer and the steam.deb on their website. None of these work. Between each I have deleted ~/Steam, ~/.local/share/Steam and ~/.steam and purged.

When Steam crashes, though, it gives no error. It just stops.

Solution 1:

I had the same issue and fixed it by purging steam:i386, removing the ~/.steam folder and then reinstalling.

sudo apt-get autoremove --purge steam:i386

mv ~/.steam ~/.steam.old

sudo apt install steam

Note that sudo apt-get autoremove --purge steam* did not remove it for some reason. I see that OP did the that, I'm not sure whether i386 was specified explicitly.
