Can't follow install prompts

[pelouk]

OK, I had another shot at it and here's the outcome:

Ran your first suggested command and here's the response:-

linux@linux:~$

Ran your second suggested command and here was the outcome:-

ii  ubiquity -slideshow-ubuntu              83.1
all          Ubiquity slideshow for Ubuntu

Not sure if that makes any sense but there you have it.  At that point I closed terminal and tried to run the install. Same result - hanging at the install screen.

I rebooted and went through the above procedures again but - on running your second suggested command - here's what appeared:-

linux@linux:~$ dpkg -l | grep 'slideshow'
linux@linux:~$ dpkg -l | grep 'slideshow'
linux@linux:~$

Strange, eh?  Well, just to complicate matters further, I tried to launch Firefox  and also to go to the forums via the menu (had to reboot between each attempt) but each action caused the screen to go a pinkish grey with diagonal stripes and just freeze for the duration.

At which point I just gave up.
