Booted the USB stick, instead the full desktop starts immediately the installer. closed the installer to test the live I had this crash.

Hello and thank you for your bug report!

probert is currently a bit lacking in terms of logging and it makes it challenging for us to understand what it is spending time on.

If you would like to help, I have prepared a script to retrieve some profiling information about probert execution. The script can be run in the ubuntu desktop installer environment and will generate a tarball with collected profiling information that you can share with us.

The script is available here in the two following locations:
* https://pastebin.ubuntu.com/p/tMrPznY8W4/
* https://people.canonical.com/~ogayot/profile-probert-desktop-installer.py

The steps to run the script are as follow:

* Boot the lunar-live-server ISO (preferably the latest daily image)
* Once the graphical interface is up and running, ignore the installer's interface and open a terminal window (ctrl+alt+t is a keyboard shortcut for it)
* Download the script using the following command (this requires an Internet connection)
    * wget https://people.canonical.com/~ogayot/profile-probert-desktop-installer.py
* Run the profiler using the following command:
    * sudo python3 profile-probert-desktop-installer.py
* The execution can take a few seconds to a few minutes.
* Once finished a tarball will be generated in /tmp/profiling-probert.txz
* Sharing the tarball with us should help us figure out what's going on. We'd appreciate it!

Thanks!
Olivier
