steam fatal error "steam needs to be online to update, but was set to offline movies."

I have installed libnss-resolve:i386 by running the following command.

apt-get install libnss-resolve:i386

And now it works for me.

Make sure steam isn't running at all in ~/.steam/.

1. Delete ~/.steam/steam.pid

2. Edit ~/.steam/registry.vdf line 29 from "Offline" "1" to "Offline" "0"

This solved it for me

sudo apt-get install xfonts-75dpi xfonts-100dpi

Try it! if first time dont work, restart!

I am running Ubuntu 17.04 and the other answers didn't solve it. I had force an entry on /etc/hosts for media.steampowered.com.

So, first get the IP with

ping media.steampowered.com
# returns 200.143.247.11 for me

then add that to /etc/hosts, like this:

200.143.247.11 media.steampowered.com

And it should work as expected.

This is a solution that worked for me with (gnome 3) Ubuntu 17.04 Install the package libnss-resolve:i386 (sudo apt-get install libnss-resolve:i386)
