Sorry you are having issues here.
If you were to use the official Debian package, then you would not be
having a problem. You could simply open a terminal in your cloned
template and run sudo apt install freeplane. This would install
freeplane 1.7 . This is generally the Debian way, but it does mean that
you are working with older versions of software.
I think you may be a little confused about where to install software - it
isn’t easy to get the hang of it.
The first thing to do is to get your Qubes running again.
Without knowing quite what you did, it’s a little difficult to help, but
let’s see what we can do.
When you are booting the x230, interrupt at the grub screen - where you
see the choice to boot Qubes. You’ll see something like “press e to
edit” - press e, scroll down to the line that start “kernel”, and add to
the end of that line qubes.skip_autostart.
Boot using that change - you’ll see on screen how to do this.
Now Qubes should start but no qubes will start.
You should be able to delete the troublesome qube - I would probably
delete everything you have done so far - and then restart.
With luck you Qubes will start as normal.
Now to freeplane.
Clone the debian-11 template to a new template, template-freeplane.
Download (as before) the debian installer, and then copy it to
template-freeplane, just as you did before. (template-freeplane will
automatically start so you can do this.)
Open a terminal in template-freeplane - In the Q menu you should see
xterm or uxterm.
Then run these commands:
sudo su
cd /home/user/QubesIncoming/NAME/
apt install ./freeplane_1.10.6u1~upstream-1_all.deb
replacing NAME with the name of the qube from which you copied the deb
file.
After the install has completed, shutdown the template.
Then you should be able to create a new qube, using the
template-freeplane.
Open a terminal in the new qube, type freeplane, and you should be up
and running.
I find that freeplane may need some extra memory - you can adjust this
in the settings window for the new qube on the Advanced tab.
If you hit a problem at any stage, please make sure you report any
specific error message.
