Use Debian then if your trouble gets out of hand. It has it on the newest distro. It's Ubuntu's big brother and Kali's big brother essentially.

Do you have 'non-free' and have you added i386 architecture in yet on your system, assuming it is 64-bit.

apt install lib32gcc1 as well. I could not get the process to run otherwise on occasion on new installs.



Googled Ubuntu and steamcmd.
Continuing with Ubuntu
