Strugling with installation

After the initial hick-ups with Lan connection, I hoped everything will be smooth sail, but it looks like no luck.
I tried a couple of times to install it from scratch, but same problem is there initramfs tools error code 1. Wondering why it looks for raspi when I am not running Rospi?
What can I do to properly finish with installation? 

Thanks,
M

After running sudo apt-get install -f I've got this:

Then went with

sudo apt-get check
apt-cache depends

I got this:
