mountall: Plymouth command failed

[Removed by request]

I'm using Ubuntu 11.10 dev with Plymouth 0.8.2-2ubuntu26. On a system boot I get the message "mountall: Plymouth command failed" and "mountall: Could not connect to Plymouth". I have seen this message after I tested this bug: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/800701

I'm also seeing somthing similar to this.

I get the 'mountall: disconnected from plymouth' during boot as described in Plymouth bug 840960
(http://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/840960)

When I boot, the four dots loading screen appears, then it disappears leaving me with terminal text showing the message:

mountall: disconnected from plymouth [OK]

After this the GUI login page appears normally and I can login as normal. When I chose to Shutdown, I again get a flash of terminal text which reads:

mountall: plymouth command failed
mountall: disconnected from plymouth [OK]

Lubuntu 11.10 upgraded from 11.04 using automatic upgrade GUI

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[DonP (forum-pc-homepage)]

I'm having the same problem suddenly after a recent update and cannot boot up at all:

Mountall: Plymouth command failed
Mountall: Disconnected from Plymouth

Mountall: Event failed

After this, there are a few gibberish characters and the system refuses to boot. If I let it sit a while, some lines about timeouts and Xrog being blocked appear but still no boot although occasionally something I press on the keyboard (I'm not sure what) will make it continue with the boot.

Is this bug still affecting people in 12.04? The one other referenced case, bug #840960, is thought to be resolved.

[Removed by request (removed3425744)]

The bug still exists in Ubuntu 12.10 dev.

Sworddragon,

Ok. I can't reproduce this bug. Please run 'apport-collect 855933' on the affected system, to gather information about how plymouth is set up for you.

Oh, whoops - of course that didn't attach any information about your plymouth setup because the bug is not assigned to plymouth. Reassigning now. Can you please run that command again?

Well, ok, here's the first problem; you have a damaged plymouth configuration, with no themes in place. Do you know how this happened?

[Removed by request (removed3425744)]

I have a minimalistic system. I have removed all unneeded packages and there are no recommended packages installed. This is uncommon but a valid installation. Maybe there is a dependency missing which is normally only installed as a recommendation. I will try to figure out if a package is mssing but maybe somebody else has an idea about this error message.

[Removed by request (removed3425744)]

The recommends for Plymouth are plymouth-theme-ubuntu-text or plymouth-theme. plymouth-theme-ubuntu-text installs only /etc/alternatives/text.plymouth and plymouth-theme is a virtual package with includes already plymouth-theme-ubuntu-text and some other themes like xubuntu-plymouth-theme which installs both alternatives. But even with this package after a reboot I'm still getting the error message.

Ah. The plymouth package has:

  Recommends: plymouth-theme-ubuntu-text | plymouth-theme

I don't recall why this is only a Recommends. Perhaps it's because you can
use the details plugin without any theme... but you're already booting
without 'splash', so that's exactly the plugin that should be used here.

That at least gives enough information to try to reproduce this locally.
Can you try installing the plymouth-theme-ubuntu-text package, to see if it
resolves the issue for you?

The result is in post #19.

Hi Steve (et al). Here's something that might help with your clues.

I'm on a headless ARM dev. board. I added an SSD drive to /etc/fstab. When the cable is not connected, I get this Plymouth error and the boot hangs. I knew it was really that the mount was hanging and booted single user to remove the fstab entry, which worked.

Hope that helps.
