/snap/ubuntu-desktop-installer/892/usr/bin/python3.10 -m subiquity.cmd.server loops indefinitely and prevents installation

[Etienne URBAH]

Systematically, the Live CD of Ubuntu 23.04 beta (Lunar Lobster) automatically starts

/snap/ubuntu-desktop-installer/892/bin/subiquity-server

which starts

/snap/ubuntu-desktop-installer/892/usr/bin/python3.10 -m subiquity.cmd.server --use-os-prober --storage-version=2 --postinst-hooks-dir=/snap/ubuntu-desktop-installer/892/etc/subiquity/postinst.d

which loops indefinitely and prevents the graphical installer to display its first question.

Sadly, when I try to pass the process number as parameter, 'apport-bug' does NOT find the associated package.
Is there an appropriate method to report a bug against a snap ?

Besides, after I kill the looping process, then the graphical installer starts correctly.
