Welcome to LinuxCNC.org

OK I think I have successfully upgraded from 2.3 to 2.4 to 2.5 and finally 2.6
Although I did not see any references to 2.6 when I did the Master branch
part of the upgrade using "Then say "sudo apt-get update" and "sudo apt-get install linuxcnc" "
how do I know if 2.6 is installed?

if you launch linuxcnc from the command line, it prints the version

If you start a config, the splash-screen has the version number.

(You might as well start the sim/remap/rack_toolchange config)

By the way: You might have lost your existing configs from the startup selection dialog. The solution is to rename ~/emc2 to ~/linuxcnc

I see two Linux wizards one familiar the other is new to me which is the best to use?

Maybe neither.
Stepconf creates parallel port stepper configs, pncconf creates Mesa-card configurations.
Neither of them automatically create a remapped toolchange configuration.

Unless I am mistaken, you had a working configuration previously? The first thing to do is check that that still works.
Then start the sim/remap/rack_toolchange config, and see if that looks like it works (it won't move a machine, it's a simulator). Make sure that you select the option to make a copy of that config in your home/linuxcnc/configs directory.

Now make a copy of your existing, working config by copying the directory and changing the name.

Then copy the extra files from the toolchange example into your config.

Then look through the INI and HAL files of the sample config, and copy anything "toolchange-ey" or GladeVCP-ish or Pythonesque into your INI and HAL files.

You will need to edit the toolchange ngc files to make the correct moves for your rack location and spacing.

Renamed the EMC2 folder to linuxcnc but my old configuration will not launch nothing happens at all

Tried using the wizard to make a new test configuration all went as usual but when I launch the test
I see a 2.5 splash then axis appears for a second then it crashes and I get the errors box.
