Hi Russell, The terminal goes through a list of actions up to No. #29 (<postRead Snapshot>:1): and the cursor sits there showing VM#. quitNoSave produces 11 errors and still leaves me at the VM# prompt. _Quit works fine. Other commands like 'help' or 'desktop open' (all without quotes) also produce 11 error messages.

I haven't found any documentation yet that says what commands should be available in the core.snapshot but working through some material in either morphic or kitchensink seems to all work fine. it's rather a steep learning curve at the moment.

Hi Colin,

When you are at the command line and do

Self -s core.snap

or your equivalent, what does your terminal show?

From the terminal you can quit without saving by ‘quitNoSave’ or ‘_Quit’

Cheers Russell

Hi Russell,

Those commands did the trick, in fact I found them in handbook once I started reading it.

I started the VM but used the 'core.snap' file and not much seemed to happen. I tried to follow some instructions in a blog but things like help or desktop open had no effect and just produced an error message. I also could not find any way to shutdown the VM, short of closing the terminal.

I see that the graphical images have a 'quit' menu item but how do you close the core VM?

I will start one of the other images and hopefully things will start to make more sense.

HI Colin, The VM is a 32 bit binary and is looking for the 32 bit versions of those libraries. You need to install these. For Debian, I think you need to do something like:

sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 libx11-6:i386 libxext6:i386

But I haven’t tried this particular magic incantation for a while.

I don’t have the time at the moment, but someone should do this up as a docker image.

Hi, Attached is the output from starting core.snap.

_Quit works because it is a primitive (primitive methods start with an underscore)

Can you cut and paste everything from your shell command up to the VM# prompt? The error messages might tell me what is going on

Cheers Russell

Hi Russell,

Apologies for all these posts, I misread your message and tried to add an attachment. Here is the text copied from terminal:
