[Bug 1705345] Re: Installing new kernel hangs on plymouth --ping

[Sven]

I have the same issue, apparently a sudo apt full-upgrade hung and I
interrupted it by shutting down my laptop. Upon trying to install
something unrelated it told me I had to run sudo dpkg --configure -a to
continue with the previous upgrade. That still hangs:

$ sudo dpkg --configure -a
Setting up linux-image-4.13.0-21-generic (4.13.0-21.24) ...
Running depmod.
update-initramfs: deferring update (hook will be called later)
The link /initrd.img is a dangling linkto /boot/initrd.img-4.13.0-21-generic

run-parts: executing /etc/kernel/postinst.d/dkms 4.13.0-21-generic /boot/vmlinuz-4.13.0-21-generic

I can see using ps axuf that it hangs on a plymouth ping, this hangs in
a terminal as well. See the attachment for the output of strace plymouth
--ping

Title:
  Installing new kernel hangs on plymouth --ping

Status in plymouth package in Ubuntu:
  Confirmed

Bug description:
  I tried to upgrade linux kernel, from 4.10.0-26 to 4.10.0-28, but the
  installation hung on the following output lines:

  sudo apt-get install unrar linux-generic linux-headers-generic linux-image-generic linux-signed-generic linux-signed-image-generic
  Configurazione di linux-image-4.10.0-28-generic (4.10.0-28.32)...
  Running depmod.
  update-initramfs: deferring update (hook will be called later)
  Examining /etc/kernel/postinst.d.
  run-parts: executing /etc/kernel/postinst.d/apt-auto-removal 4.10.0-28-generic /boot/vmlinuz-4.10.0-28-generic
  run-parts: executing /etc/kernel/postinst.d/dkms 4.10.0-28-generic /boot/vmlinuz-4.10.0-28-generic

  Then I looked at the running processes, and noticed this one was
  blocking post-installation:

  plymouth --ping

  I could not but manually kill plymouth, then the script resumed just
  to freeze again a few line later and so on, but is that safe for the
  installation?
