[Bug 1768025] [NEW] recovery mode hanging

[Hadmut Danisch]

Public bug reported:

Hi,

I've reported this yesterday as a single bug, #1767685 , but further
debugging showed that it seems to be two distinct bugs.

I've installed Lubuntu 18.04 on another machine today and had the same
problem, recovery mode hanging after activating the network. (using an
encrypted partition). Although the recovery mode hangs, the systemd
debug shell is working and I found from systemctl status:


    State: initializing
     Jobs: 78 queued
   Failed: 1 units
    Since: Mon 2018-04-30 15:02:45 CEST; 36s ago
   CGroup: /
           ├─init.scope
           │ └─1 /sbin/init recovery --startup-event=recovery
           └─system.slice
             ├─debug-shell.service
             │ ├─378 /bin/bash
             │ └─962 systemctl status
             ├─systemd-udevd.service
             │ └─583 /lib/systemd/systemd-udevd
             ├─systemd-journald.service
             │ └─377 /lib/systemd/systemd-journald
             └─friendly-recovery.service
               ├─403 /bin/bash /lib/recovery-mode/recovery-menu
               ├─591 /bin/sh /lib/recovery-mode/options/network
               ├─595 systemctl start dbus.socket
               └─602 /bin/systemd-tty-ask-password-agent --watch


The system hangs in systemd-tty-ask-password-agent. Killing 591 /lib/recovery-mode/options/network makes the system go back to it's options selection menu and open a recovery shell. 

So that's where the system hangs.
