Following the Debian Live manual on using a predefined configuration(https://live-team.pages.debian.net/live-manual/html/live-manual/managing-a-configuration.en.html#333):

$ cd images/standard
$ sudo lb build
...this works and I get an ISO image in that directory.
But, instead doing this:
$ mkdir live-images && cd live-images
$ lb config --config https://salsa.debian.org/live-team/live-images.git::debian
$ cd images/gnome-desktop
$ sudo lb build
(note the change in the 'cd' command)
...this does NOT work. The build command starts doing a lot of work, fetching & installing stuff, but then simply stops at this point (copy/paste of ~17 lines of build.log):
It's not mentioned in those docs, but I'm pretty sure you'll need to
run 'lb config' one more time after moving to the config directory
(and possibly editing the files inside), before 'lb build'.
Interesting. I've tried it, but it doesn't make much of a difference - stops at roughly the same point (well, I get two lines extra, but not much information from that).
I did manage to trace the root cause back to lines 75/76 in /usr/lib/live/build/chroot_package-lists:
Expand_packagelist "$(basename ${LIST})" "config/package-lists" \
| grep -v '^#' >> chroot/root/packages.chroot
It seems that at some point, with the config I'm using, "Expand_packagelist" does not return anything and the script then simply stops. When I replace it with:
My_list=$(Expand_packagelist "$(basename ${LIST})" "config/package-lists")
echo ${My_list} | grep -v '^#' >> chroot/root/packages.chroot
...the build continues and delivers a bootable image. So, my issue seems to be solved with that, or at least I have a workaround. Perhaps I'll dive a bit further, because right now I don't fully understand why the build would stop originally: I would expect, if "expand_packagelist" doesn't return anything, that the following "grep" would hang indefinitely.
