Could you provide the logs from /var/log/installer/ please? I've yet to
run into this on my tests.

Bug description:
  I connected the system to wifi using gnome's settings.

  Stuck at the "Preparing Ubuntu..." screen burning 100% cpu on one
  core.

  The process burning CPU (currently at 27m runtime) is:

  python3 -m subiquity.cmd.server --use-os-prober --storage-version=2
  --postinst-hooks-dir=/snap/ubuntu-desktop-
  bootstrap/107/etc/subiquity/postinst.d

  strace shows no output when run for several seconds, so no syscalls in
  the hot loop

  I generated a core dump of the running process using GDB, but at 627M
  I don't think it is going anywhere. When I attach with gdb I see:

  0x00007f23d27ce5bb in nl80211_get_ie (ie=0 '\000', ies_len=<optimized
  out>, ies=<optimized out>) at probert/_nl80211module.c

  
  warning: 378  probert/_nl80211module.c: No such file or directory
