SteamOS has an immutable root filesystem. You cannot install regular packages without first disabling that, and even if you did, the changes would just get overridden at the next OS update.
If you want Chromium, you will need to install the flatpak version from the Discover app.
Yea, that's what I've heard. Steam OS is basically a locked down OS, they discourage the use of apps outside of the Discover app store. I think I'm going to give up on using it for more than gaming, I'll setup dual boot Windows 10 on it once Valve releases the official dual boot support.
