Bug#1028369: debian-live: screen lock demands a password

[Forest <forestix@sonic.net>]

Package: debian-live
Severity: normal

Dear Maintainer,

While installing from the kde+nonfree debian-live-11.6.0 image,
the screen lock engaged, demanding a password to regain control
of the session.

Of course, since this is a live ISO image, I didn't know the
password. I had to find another computer and search the web
for a while, eventually finding someone who correctly guessed
that the password is "live", before I could continue the
installation.

I suspect this is a mistake, and that there should be no password
set on the live user account.
