The main problem is that I can't install Steam basically, but I tried with other applications too and none of those applications will install.
I run software center via terminal and this is the log that i get when i try to install steam.
I click on steam and then I click on buy, it redirects me to login and I login, so authentication pass and I'm logged in but I still get an error to buy application again and this time it won't redirect me to login, it just won't install.
Here's log file

From the last line I see authorization failed but I don't know if this is authorisation to Ubuntu but i have already logged in.
The second time when I tried to install the application I started software-center via terminal and went to file > install previous purchases, and there was steam. When I clicked I had install button instead of buy but still wasn't able to install it.
The same thing happens when I try to install filezilla or any other app.
I even reinstalled complete OS and again having same problem. Now i don't even have terminal to start it from there.
