Please describe your issue in as much detail as possible:

I had to reinstall Steam today, as it was displaying an error popup when I tried to launch it. I don't really remember what was the error about, it probably isn't related to the current issue and to be honest, I am not even sure if I ran Steam on my current installation and didn't just have the icon on desktop left from when I was transferring my /home.

So I removed the icon, did all the sudo apt remove steam-launcher, sudo apt autoremove and installed steam according to the instructions on [https://repo.steampowered.com/steam/]. Everything seemed to install properly. When I tried to run steam, there was the small gray progress-bar windows saying something like "Updating Steam/downloading XXX MB...", the usual stuff. When everything finished downloading, this small window closed, but the launcher window never came up.

After waiting for a long time, I opened system monitor/task manager, shut down anything steam related and ran ~/.local/share/Steam/steam.sh. Terminal output looked promissing at first, but after a while, it seemed get stucked in an infinite loop and repeating the same output again and again. The repeating output was:

So I decided to check the cef_log.txt file and it looks like the problem is logged in it:

Steps for reproducing this issue:

1. Get my machine
2. Install as I did
3. Run as I did

Sorry guys, I don't know how else could this be reproducable.
