[Bug 1766872] Re: 'Enable Network' in recovery mode not working in Bionic

 

Test packages[1] are available for Xenial/16.04 & Bionic/18.04 on my
PPA[2]. I did some preliminary test which seems to work as expected.

Please anyone affected test the packages, and keep me posted.

[1] - Test package 
Xenial - friendly-recovery - 0.2.31ubuntu1+testpkgb2 
Bionic - friendly-recovery - 0.2.38ubuntu1+testpkgb1 

[2] PPA 
sudo add-apt-repository ppa:slashd/test 
sudo apt-get update 
sudo apt-get install friendly-recovery 

Regards, 
Eric

Bug description:
  This bug has been noticed after the introduction of the fix of (LP:
  #1682637) in Bionic.

  I have notice a block in Bionic when choosing 'Enable Network' option
  in recovery mode on different bionic vanilla system and I can
  reproduce all the time.

  I also asked colleagues to give it a try (for a second pair of eye on
  this) and they have the same result as me.

  Basically, when choosing 'Enable Network' it get block or lock.
  If we hit 'ctrl-c', then a shell arrive and the system has network connectivity.

  Here's what I find while enabling "systemd.debug-shell=1" from vtty9 :

  # pstree
  systemd-+-bash---pstree
          |-recovery-menu---network---systemctl---systemd-tty-ask
          |-systemd-journal
          ....

  # ps
  root 486 473 0 08:29 tty1 00:00:00 /bin/systemd-tty-ask-password-agent

  root 473 486 0 08:29 tty1 00:00:00 systemctl start dbus.socket

  root 486 283 0 08:29 tty1 00:00:00 /bin/sh /lib/recovery-
  mode/options/network

  Additionally,

  systemd-analyze blame:
  "Bootup is not yet finished. Please try again later"

  "systemctl list-jobs" is showing a 100 jobs in 'waiting' state

  The only 'running' unit is friendly-recovery.service :
  52 friendly-recovery.service                 start running

  The rest are all "waiting". My understanding is that "waiting" units
  will be executed only after those which are "running" are completed.
  Which explain why the "ctlr-c" allow the boot to continue.

  All the systemd special unit important at boot-up are waiting.
  7 sysinit.target                 start waiting
  3 basic.target                   start waiting
  .....

  Seems like systemd is not fully initialise in 'Recovery Mode' and
  doesn't allow any 'systemctl start' operation without
  password/passphrase request, which I suspect is hidden by the
  recovery-mode menu.
