Thank you for reporting this bug. It sounds similar to something that I'm seeing. Can you try one thing to confirm this:

Boot the live DVD, select restart, wait until the hard drive activity stops (or just wait a good minute or two), then press the enter key and see if the system reboots.

That is the behavior I'm seeing. I simply see the desktop background, which seems to suggest that's it's not hanging, but rather that plymouth is simply not drawing the shutdown splash correctly.

Hi Chad A. Davis ,

I have restarted like you told me and this time it has shutdown correctly.

Best Regards

This is not a bug with the installer, ubiquity, rather it is one with the live environment and or Kubuntu itself.

I've had similar experiences on a kubuntu install on my main machine - not virtual box.
I select shutdown, the screen greys out a bit - but all the apps are still running and it doesn't get any further; I can still type in a konsole and do a sudo shutdown -h now

Having said that, it's got more broken now, the shutdown option has disappeared from the leave menu - that's bug 853294


Has anyone yet found the cause?

I'm having a hard time figuring out how this problem is only of Medium importance. Maybe it hasn't been reported enough, and if there is another bug report on this issue, I cannot find it.

I am using the latest daily build live-cd, and every time I have to put in my user password, be it to install a piece of software in Muon Package Manager, or open a folder as root, there is a very good chance I will not be able to shut down. My guess is that this is the only common factor preceding a hang on shutdown. Just as Dave Gilbert wrote: "I select shutdown, the screen greys out a bit - but all the apps are still running and it doesn't get any further; I can still type in a konsole and do a sudo shutdown -h now." In my opinion, this is a huge problem for ordinary users.

I was able to reproduce this on a laptop, a Toshiba Satellite L305-S5937, with and without Plymouth enabled, so the problem still occurs even when there is no shutdown splash screen or animated progress bar.

I hope this is addressed before release.

Also, I am not using virtual box. I am talking about an installed system.

Well, updating with xorg-edgers (as a last resort), fixed the installed system problem on this hardware.

Analysis while checking #837870:

1. Run KDE Partition Manager from the Live CD.
2. Modify something so an operation is added to the list of pending operations.
3. Quit the application without applying operations. It will ask if you really want to quit, spawning a knotify process to do that.
4. Agree to quit without applying operations.
5. Shutdown the system. It will ask for confirmation, then just sit there, apparently fully usable.
6. Find root's knotify process in a shell. Kill it.
7. Shutdown proceeds.

Note the behaviour has probably nothing at all to do with KDE Partition Manager. It's just one application that spawns a knotify process.

This issue should probably be taken to if it's not there already.

Not casper's fault and no obvious workaround to do in casper, moving back to Ubuntu for triaging.
