Kubuntu 14.04.2 freezes after booting

[Steckerl]

Hi all,
after fresh installation of Kubuntu 14.04.2 LTS i installed VB 4.3.24. At the next reboot the system freezes during the start splash screen.
The reason therefore is a no more accomplished dependency: the ubuntu team has updated the kernel and X stack (refer to ​https://wiki.ubuntu.com/Kernel/LTSEnablementStack). So during installation of VB the putative accomplishment of libgl1-mesa-glx leads to removing a large number of packages coming with libgl1-mesa-glx-lts-utopic.
Thus i suggest to include libgl1-mesa-glx-lts-utopic into the dependencies list like
..., libgl1-mesa-glx-lts-utopic | libgl1-mesa-glx | libgl1, ...

VirtualBox 4.3.24 works well on most machines with Ubuntu 14.04 installed. Which package of VirtualBox did you install (exact package name please)? I don't see any dependencies of the official package from this server which couldn't be satisfied by the Ubuntu repository.

Hello Frank,

i've installed virtualbox-4.3_4.3.24-98716~Ubuntu~raring_amd64.deb, downloaded from the virtualbox website. But the important thing is, that the described error only occurs on a fresh, original installation of Kubuntu 14.04.2! Only in this case the libgl1-mesa-glx is no more installed, but the new libgl1-mesa-glx-lts-utopic. The failure also doesn't occure, if you've updated from Kubuntu 14.04.0 / 14.04.1 to 14.04.2.

To verify this, have a look into installed kernel and packages:
updated to 14.04.2: kernel-version is 3.13.x and libgl1-mesa-glx
original 14.04.2: kernel-version is 3.16.x and libgl1-mesa-glx-lts-utopic

I don't know what we should look at. Linux 3.16 is very well supported with the current VirtualBox 4.3.24 package. I just did the test and installed Kubuntu 14.02.2 / 64-bit from scratch. After that I installed the 4.3.24 VirtualBox package (dpkg -I virtualbox-4.3_4.3.24-98716~Ubuntu~raring_amd64.deb; apt-get install -f'), then I rebooted the host (not necessary) and was able to start a VM.

Also, it's very unlikely that a host freeze after a host reboot is a VirtualBox bug. It's true that VirtualBox installs kernel drivers but as long as no VM is running, these drivers are inactive.

Hi again,
now i've tried the way you described and it worked also for me! But my way was installing VB with QApt-PackageInstaller; performing the installation this way, the Package Installer tells me, that it requires the installation of 50 additional packages:
installation of (among others): libgl1-mesa, but to remove 39 packages. If you confirm the installation, the disaster starts.
After the installation you're able to start VB and all seems to be good, until the next reboot...
I agree with you, that this isn't a problem of VB, but if you include libgl1-mesa-glx-lts-utopic beside libgl1-mesa-glx within the section dependencies (within the file control), you can avoid this setting.

Hi Steckerl, I understand your problem but we can really not provide extra packages for Kubuntu 14.04.2 because adding dedicated dependencies would mean to make this package unusable on other 14.04 distributions. I see that our package drags in some packages and the package manager might chose the wrong packages but this is nothing we can fix.

I will close this ticket as "wontfix" and hope that you agree.
