Could not find the very same problem elsewhere.

Config is : i5-4590 on ASrock H97M Anniversary, 16GB RAM, GTX 970 from ASUS. Ubuntu 15.04 and drivers Nvidia 352.21.

When start Steam, I got the verify for update popup, then it crashes.

I have the below trace

User@PC:~$ steam --verbose

Where should I start?

  • Have you attempted sudo apt-get --purge remove steam && sudo apt-get install steam? – DJ_Beardsquirt Jul 15 '15 at 12:44
  • in doubt, I just tried that and end up with the very same result. – Memes Jul 15 '15 at 15:21
