[SOLVED] - VirtualBox Not Updating Due To Error "Breaks existing package..."

The 'Breaks existing package' error usually happens when you are trying to update VirtualBox from say version 5.0.x to 5.1.x. To resolve this issue you will first have to uninstall VirtualBox. Open your terminal and enter the commands below:

 sudo apt-get purge virtualbox-*  

Now install VirtualBox using the code below. But first find the version number of the latest VirtualBox package available by visiting the following page: https://www.virtualbox.org/wiki/Downloads. When I checked the latest VirtualBox version available was: VirtualBox 5.1.22.

 sudo apt-get update  
 sudo apt-get install virtualbox-5.1.22   

After upgrading VirtualBox you will also have to update your Extension Pack. You can download the Extension Pack from the aforementioned page.

[[SOLVED]] - Accidentally Deleted Snapshot in VirtualBox and OS not Booting in Ubuntu 14.04

If you happen to accidentally delete your 'Snapshot' files and have been getting an error as - 'vd: error verr_file_not_found opening image file;' read further for the solution:

If your VM is in the 'saved state' first you will have to the discard the saved state to make any changes. To do so in your VirtualBox Manager go to Machine and then select 'Discard saved states' or press 'CTRL+J.' As the prompt indicates this will be equivalent to switching off your system and now you can make the required changes.

Now go to File menu and select 'Virtual Media Manager' or press 'CTRL+D.' Release the snapshot displayed with a red mark and also Delete it.

Now you will have to select the original 'vdi file' that was created during your installation process. To do this Select Modify and go to the location where you have installed your VirtualBox and select the 'vdi file'  and Restart.

Your problem should be RESOLVED now.

Enabling USB WiFi Network Adapter in VirtualBox with Kali Linux as Guest OS

I found enabling USB WiFi Adapter in Window 7 much simpler than Linux, precisely Kali Linux. Not that I couldn't do it in Kali but after sometime the connection would drop. But with Windows 7 it didn't take me a fraction of time compared to Kali and with the method I discovered the connection is also not dropping in Kali now.

So here's how to do it with Kali Linux as Guest OS. You can also use the same technique while using other OS such as Windows as Guest OS:

1. First make sure you have  added yourself to the user group 'vboxusers'; else you will be unable to view your Wireless USB Network Adapter under the  USB Devices list.

2. Now you can select your Network Adapter by going to --> Devices -->  USB Devices --> Select your Network Adapter here

Now to save yourself from your 'connection getting dropped' every now and then, make sure you have disabled your Internet connection from your Host OS. See the image below.

 

To confirm your WLAN setup Open your terminal and type:

 ifconfig  

You should be seeing something like wlan0 along with the details as in the image above.

6. Select Auto-mount if you would like to mount your drive/folder/file on startup.
7. Finally Click OK and that's all there is to 'Sharing Folders' in Virtual Box.

How To Resize Virtual Hard Disk Size In Ubuntu

If you are running out of Virtual Hard Disk space in your VirtualBox environment and looking to increase space - follow the instructions below:

Syntax:

 sudo VBoxManage modifyhd "vdi location" --resize "new size in MB"  

Example:

 sudo VBoxManage modifyhd '/home/evagabond/VirtualBox VMs/Windows/Windows 7 (x64)/Windows 7 (x64).vdi' --resize "61440"  

Please note that if your location address contains spaces it's better you insert it within single quotes as I've done in the above example to avoid error in the terminal.
