Installation on Ubuntu14.04 hangs

Hi,
I've an issue with the installation process.
All works fine until it try to install mysql-server package.
The server is in idle, no process is working and CPU is at 1%... Above the logfile.

Now, since the server is in that situation from 3 hours... what can I do?
If I stop the process, how can I resume it?
Uh... this is already the 2nd time I try, first time with the same result.
My server is Ubuntu 14.04 LTS.

Thanks
