Hello @Patatone, I read that log as steam suggesting you need libdrm2:i386. Libdrm-dev should only be needed for building packages, not the running system.
Same error dialog box here, but different output at the command line:
$ steam

Hello @dinsdalepiranha, you'll want to run sudo apt install realpath and if needed, remove ${HOME}/.local/share/Steam/ubuntu12_32/steam-runtime/pinned_libs_* so that steam will regenerate those folders.
Just installing realpath allowed Steam to update and resolved this for me (I had no files at the path you listed). Thanks!

I would have expected that to read libdrm2:i386 is already the newest version (2.4.74-1), for the 32 bit variant.
Nothing extracted yet.

I tried to install libdrm-dev but the system told me that it's already installed.
Thanks for the help :)
