You should get the latest downloads from https://coreform.com/products/downloads/. There’s a .deb installer there that should install everything automatically for you.
Thanks for your reply, Sir. I managed to install it. However, I don’t know how to start it. Is there any manual or any tutorial to use it from ubuntu?
Best regards,
Lovepreet

The error you’re showing can occur when you either don’t have a graphical environment (you only have a terminal) or your graphics aren’t configured correctly. If you don’t have a graphical environment, you can use Coreform Cubit from the terminal only by passing the flags -nographics -prompt Cubit, like this:
coreform_cubit -nographics -prompt Cubit
If you do have a graphical environment, then you can take a system call log like this;
strace -o debug_cubit.txt coreform_cubit
Please attach the generated debug_cubit.txt to this post and we’ll help you figure out the issue. If you don’t have strace, you can install it with
sudo apt-get install strace
Thanks for your reply Sir,
I have already tried with coreform_cubit -nographics -prompt Cubit and it asks me the licence
I tried to follow https://coreform.com/support/activation/cubit/activateoffline/ for offline activation, however, the activate tab does not appear in my window (maybe due to Coreform Cubit learn version).
Regarding the second command
strace -o debug_cubit.txt coreform_cubitI have attached the resulting file (in pdf version since .txt is not allowed)
debug_cubit.pdf (341.3 KB)

The graphics error is this:
socket(AF_UNIX, SOCK_STREAM|SOCK_CLOEXEC, 0) = 4
connect(4, {sa_family=AF_UNIX, sun_path=@"/tmp/.X11-unix/X0"}, 20) = -1
ECONNREFUSED (Connection refused)
close(4) = 0
socket(AF_UNIX, SOCK_STREAM|SOCK_CLOEXEC, 0) = 4
getsockopt(4, SOL_SOCKET, SO_SNDBUF, [0], [4]) = 0
setsockopt(4, SOL_SOCKET, SO_SNDBUF, [65536], 4) = 0
connect(4, {sa_family=AF_UNIX, sun_path="/tmp/.X11-unix/X0"}, 110) = -1 ENOENT
(No such file or directory)
close(4)
That means that Cubit is attempting to connect to a X11 socket (that’s your graphics display) and the connection is being refused. Are you connecting to this machine via SSH? You may need to configure X forwarding, or there could be a permissions issue.
For a Cubit Learn license you will need the graphics to work in order to activate.
Thank you for your reply, Sir.
I managed to run Cubit GUI application through Xephyr.
