Virtualbox installing error

You don't need to put download.virtualbox.org in the software sources. The PUEL edition of VB will tell you when it an update is available and this is one case where you are better off doing it yourself.

I also can't see any evidence that you actually installed the PUEL edition: what you did will only add the website to the sources and added a signing key for it. You should probably open up "software sources" and delete the additions you made, and also under authentication you may remove the key for VirtualBox.

Now fix any broken or partly installed packages that may cause you problems:

sudo apt-get -f remove
sudo apt-get autoremove

Which version do you actually want to install? If it's the OSE edition (open source edition) then you only have to open up the software center and install it from there.

If you just have to use command line instead of Software Center then the command

sudo apt-get install virtualbox

will select and install the latest version.

If you are still having dependancy problems after this we'll have to look a bit deeper into it.

If this doesn't fix the problem when you try to install the

Go in synaptic and check if ose version is installed.If it is remove it completly.After that in terminal

sudo apt-get -f install

to fix broken packages.

I have removed the addition made in the software centre and also all the keys . But still the problem is same .
the outputs are

Now by mistake I have deleted all the keys. Is in create any other problem ? If yes then how to get back them ?

thanks for replying...

@zvacet (ivicakolic)

I have checked synaptic and no OSE version installed. and also run the command suggested by you and submitted the output above. thanks

Add Medibuntu repo key following https://help.ubuntu.com/community/Medibuntu

try to add other keys with

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5

and for every other just change number at the end of command

thanks for the advise about keys. But still I am unable to install virtualbox. Actually I am using a old and non LTS version of ubuntu (10.10). So I want to test the new versions. So this is urgent about testing my backups and also for the new versions . Please advise how can I install ? From software centre still giving the same error as bellow

''This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.
Details:
virtualbox-ose-qt''

Bellow the error message there is an ok button clicking on that a message is flashing that is
"Items cannot be installed or removed until the package catalog is repaired.Do you want to repair it now?
Once Update Manager has finished the repairs, you can close it and return to the store."

then there is two button "Cancel" & "Repair"

How to repair ??
need help..
thanks

VirtualBox has a dedicated forum for Ubuntu host. You could also request help here:
https://forums.virtualbox.org/viewforum.php?f=3

If you want to test new version of Ubuntu, you can do this from a USB stick, with a persistent area.

Thanks zvacet, that solved my question.

Thanks a lot all of the above members for response .......thanks . Virtualbox is successfully installed.
