I had installed VirtualBox but it started giving me problems. So I uninstalled it using:-
sudo apt-get remove virtualbox-\*
sudo apt-get purge virtualbox-\*
But when I reinstalled VirtualBox it again resumed to previous settings and started giving same problems. How can i completely remove VirtualBox from my laptop and then reinstall it such that it wont give same problem again?
Your problem : Virtual Box keeps its folder and settings in your home folder. Delete everything inside the folder.
Uninstall VirtualBox first.
sudo apt-get remove --purge virtualbox
Run these commands to delete all virtual machines and settings and Virtual Hard Drives:
sudo rm ~/"VirtualBox VMs" -Rf
sudo rm ~/.config/VirtualBox/ -Rf
If you want to install it again. Run this command:
sudo apt-get install virtualbox
Additionally, check:
sudo ps aux | grep -i "vbox"
Kill any "ghost" processes you may think are relevant.
sudo pkill VBox*
sudo apt-get remove virtualbox* --purge
Just try one command for remove all VM. Or perticulary one VM
sudo apt remove virtualbox virtualbox-5.0 virtualbox-4.*
After that, you maybe get some instruction which will already give there you just need to type on the command line. Then again run same above command.
First find installed package using below command :
sudo dpkg -l | grep virtualbox
Then copy packages and remove using dpkg or apt-get as below :
sudo dpkg --purge <Packages>
--force-all optional
And also manually remove folder on home directory (~/"VirtualBox VMs").
If you installed VirtualBox through the installer script, you can find the directory where it is installed by running
cat /etc/vbox/vbox.cfg
You can then run the uninstall script located in the install directory. Assuming it's installed to /opt/VirtualBox, run
sudo /opt/VirtualBox/uninstall.sh
sudo rm -rf /opt/VirtualBox/
Open the terminal and type:
sudo apt remove virtualbox unity-scope-virtualbox ^virtualbox-
If you installed VirtualBox from the Oracle website find your VirtualBox version as follows:
sudo apt install aptitude
aptitude search virtualbox\*
The latest version of VirtualBox that has Oracle VM VirtualBox on the same line with it is the package you have installed. If you have the latest version of Oracle VirtualBox installed, it is named virtualbox-5.1.
Verify that this version of Oracle VirtualBox is currently installed.
dpkg-query -s virtualbox-5.1
Uninstall Oracle VirtualBox using a command that looks like this:
sudo apt remove VirtualBox-5.1
If you have a different version of Oracle VirtualBox installed replace VirtualBox-5.1 in the above command with your VirtualBox version.
Your problem is not with VirtualBox, it is with your kernel. You appear to have somehow run into an issue which caused a mismatch.
Simply run sudo apt update && sudo apt install -f as you've been instructed by the system, and it should install the correct packages.
Once this is completed, I recommend rebooting (just to be safe, though it is not absolutely necessary), and then running sudo apt remove --purge *virtualbox* to remove VirtualBox and any related packages.
If you don't run sudo apt install -f, you're going to keep running into this problem with pretty much any package, as the package management system is left in a broken state until that issue is resolved.
