Bug Description


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: /
           │ └─1 /sbin/init recovery --startup-event=recovery
             │ ├─378 /bin/bash
             │ └─962 systemctl status
             │ └─583 /lib/systemd/systemd-udevd
             │ └─377 /lib/systemd/systemd-journald
               ├─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.
