Bug Description

I have downloaded Kubuntu 16.04 daily build 20160416 and created an installation USB stick with USB Creator.

After booting from the stick the boot screen appears with alternatives: Start Kubuntu, OEM installation and chck disc. I choose Start Kubuntu.

The Kubuntu logo flashes for a few seconds and then there is an awful lot of Plasma chrashes. Some information is given in crash report windows: "Executable: plasmashell PID:2109: Illegal instruction(4)". The PID:s vary a lot: 2089, 2153, 2166, 2186, 1910 etc. It's not possible to restart plasma or communicate in any other way with the computer except closing the bug report windows. When done the screen is just black with a mouse pointer (not frozen) but there seems to be no way to continue or even bring forth a command shell. Hard reboot.

I have tested the same stick on two computers, both with UEFI, but with different hardware. (Computer 1 Desktop: Intel Skylake 6500 Nvidia graphic card, Computer 2: laptop Intel 5200U, Intel HD4400). Both fail. I have downloaded the disc image several times and reformatted the stick. I have booted from different USB ports, USB2 and USB3, and nothing has worked. I have also tested the same stick with Ubuntu and Xubuntu daily builds from the same day and they work without problems.

So it seems that the Kubuntu installer for 16.04 is broken. Other flavours are unaffected.

I cannot reproduce this exactly. I had one computer that would not boot to an X environement. But was able to startx. Nvidia card. Installed on computer with Intel card no problem.

In short, we need those logs to be able to get anywhere on this bug.

Yes, I understand that you must have additional information.

Sorry, but Alt + F2 does not work. Just messages about additional crashes (krunner if I remember correctly).
I might however have found another way. I burned a DVD from the ISO and tried to start Kubuntu. It did not work either, but there are some messages on the screen that might/might not be useful, see the attached image. I will try some more experiments to retrieve more information and I am open to suggestions.

ALT+F2 opens KRunner - It's ALT+CTRL+F2 _this opens a virtual Console (TTY2) to return you press ALT + F7

Some people call this rescue-console

In TTY2 you could just login username: kubuntu password: just leave it blank

Once you are loooged in type "startx" (w/o marks)

Then you could toogle to /var/log/

interesting would be gpu-manager.log

Someone on the german ubuntutuusers.de forum wrote in the Ubuntu+1 channel that it worked flawless as he being on a hybrid graphics machine activated the hybrid-graphics mode in the UEFI-Bios - not knowing if he ticked the "install third-party drivers" or if he just relied in Nouveau+Intel-XOrg drivers

Sorry, but ALT+CTRL+F2 takes me nowhere. Just a blinking prompt with no possibility to issue any commands. No virtual console. Therefore I can't startx or reach /var/log/.

I have a discrete Nvidia card, desktop, and Intel graphics on my laptop.

It's weird since I have now tested the new daily build of Xubuntu (20160419) and it's working flawlessly. It's just Kubuntu that is affected.

I have downloaded the latest daily build of Kubuntu (20160419) and put the ISO on my thumb drive. The same plasma crashes. The good thing is that if booting from USB I am able to reach the console via ALT+CTRL+F2. The bad thing is that startx does not work. There is just another crash message: "All shell packages missing. This is an installation issue, please contact your distribution". Sounds kind of bad...

I'll see if I can reach some logs under /var/log/ so far no luck.

Seeing this on a Kubuntu 16.04 installed a few weeks ago from the beta2 install CD. This installation worked fine until today, I am getting a pop-up after logging in:

Plasma Cannot Start - Plasma

All shell packages missing.
This is an installation issue, please contact your distribution

Krunner works in my case and I can start programs like this.

Stijn Tintel (stintel) wrote :

Correction, downgrading to plasma-desktop-data_5.5.4-0ubuntu1_all.deb made the pop-up go away, and I could start plasmashell again. However, my panel was still messed up and clicking kickoff produced an error.

I then noticed that plasma-desktop was not installed (showed rc in dpkg -l), so I manually installed plasma-desktop_5.5.4-0ubuntu1_amd64.deb and now everything seems fine after logging out and in again.

I can partly reproduce this from an earlier Virtualbox installation. After update Kubuntu started and plasma-desktop was still installed. kubuntu-desktop was however missing and by installing it a bunch of other packages was reinstalled too. So perhaps the latest plasma removed vital packages.

So, I retested the final images (20160420.1) in both Virtualbox and on my nvidia optimus notebook.

The virtualbox session crashes the install/live session screen (known issue) and threw me into a fully functional plasma session. While kubuntu-desktop is indeed not installed, the installation itself worked fine, and after resetting the system I had no problems booting it.

On my notebook (on the intel GPU), the live session experience was exactly the same, but I did no install test.

It would be great if someone with such a failed system could try to get a wired network connection, and run 'ubuntu-bug ubiquity' from there and open the bug reporting URL from another system (or write it down).

If switching to a TTY doesn't work, The recovery mode from the GRUB "Advanced options from ubuntu" section has an option to drop you to a root shell. That should gather enough logs to tell us why plasma-desktop etc. was missing.

If you still cannot file a bug with apport with that, try to at least get the logs from /var/log/installer and /var/log/apt - that can even be done from a Kubuntu 15.10 live session

I was confirmed a new situation in this problem. It is to encounter this bug in the "language-dependent".

I was to proceed with the installation in English, was able to start up properly.
But I installed under the same conditions in 日本語(Japanese). As a result encountered in this problem.

Try you install in language other than English in order to confirm this problem.

I can confirm this is a problem on my system too. I have booted to the 16.04 LTS release ISO on a USB stick, and I get three separate Plasma crash screens, all invalid instruction exceptions.

System details: Asus H110M-A motherboard, 16GB RAM, Intel core i3, Nvidia GTX950.

dmesg reports that after 19 seconds or so the "nouveau" process has crashed. Engine 7 client 6 reason 2 channel 2

I switched to internal graphics and it then worked OK, so it looks like it's an issue with the NVIDIA graphics drivers. I will try installing it in this mode, then update the drivers and report back.

Since I am not used to this kind of work it took some time to retrieve them. Perhaps someone could have guided me.

Some further experiment show that nomodeset in grub makes Kubuntu boot to the screen where you choose to "Try Kubuntu" or "Install Kubuntu". If you choose "Try Kubuntu" the Live session crashes as before. I have not tried the Install option. This is my production machine and I can not experiment on it.

kubuntu 16.04 is about 2 months out, and there is still no installable version? dpkg status of plasma-desktop is rc and there is no way to change it because it conflicts with language and other files. That problem actually appeared already in one of the previous releases, but misteriously disappeared again. But now already the installer is broken and the packaging system's force and ignore options, which did exist in the past, are gone as well...

I downloaded Kubuntu once more and run the installer and it crashed exactly like before. It is still impossible to install Kubuntu. So nothing is fixed. Should you not at least distribute new ISO:s?

Since the crash happens before any language selection I believe that there are different bugs in play. I can not install Kubuntu even in English and I don't think this bug is a duplicate of 1576455.

Removed the duplicate marker. The translation issue only appears once you are already in the installer sequence. But for that you at least need to get a working Live Session first.

I have no chance to tick any alternatives. The Installation never starts. Thus there are no installation logs either.
As I posted in comment 30 I suspect the bug is related to this one: https://bugs.launchpad.net/ubuntu/+source/llvm-toolchain-3.8/+bug/1564156 and has nothing to do with missing language packs. Since there are an alternative in Ubuntu and other Buntu flavors to install without starting the live session, it is possible to install and download necessary updated during installation despite the bug (as I am able to verify). Since this is not possible in Kubuntu, users with modern hardware similar to mine are stuck.
I think it is really bad to release a LTS-version with such a bug.

I can confirm this is related to llvm bug (at least in my case) and seems to happen on i7 skylake (6th generation). I have 16.04 live image installed on usb and had the same problem - illegal instruction in plasma. I managed to solve this simply by updating libllvm3.8 from 1:3.8-2ubuntu1 to 1:3.8-2ubuntu3 (i had persistent storage enabled on the usb).

Once 16.04.1 iso is out, this will probably be resolved as it should (hopefully) contain updated version of libllvm.

I have a new installation of KDE neon as based on the Kubuntu 16.04 LTS.
As a result, KDE neon is started successfully.
I think there is improvement, even Kubuntu from this result, after I was live started in Kubuntu 16.04 ISO,
also put the following command in Konsole:

$ sudo apt update
$ sudo apt install ubiquity (not "upgrade")

Then was installed, Kubuntu has booted successfully.

This problem seems to be in ubiquity.
Because you are starting the ubiquity before you run the "Download updates during the Installation",
it does not solve. Run the apt.

Congrats to Kubuntu 16.04!
