When you want to share clipboard, drag'n'drop and share folders to your guest computer from host computer, it requires you to install an image (ISO) file. That's the ISO file. Download this, use when VirtualBox asks you for guest addition ISO, install on guest side, and then functions just work. That's an optional package but I'd strongly recommend it, you'll never know when you gonna need it.
Mint 18.3, problem with installing solved. You must use Nvidia drivers for Linux, instead of open source. This package seems to be the only way, to run guest OS (Windows 10) at 1920x1080. So before installing - check which driver is installed and in use.
Mint 16 works out of the box with it's own version installed, this breaks it. Don't install.
No unistall problems: "0 to upgrade, 1 to newly install, 0 to remove and 0 not to upgrade."
Worked for me. Virtualbox is still installed and runs. Maybe the package is fixed now.
WTF! this package have uninstalled my virtualbox completely!!! DO NOT INSTALL IT
Check /usr/share/virtualbox, there should be VBoxGuestAdditions.iso already, no need to install this package.
I agree with the last poster. I love VirtualBox, but this version of the guest additions caused VirtualBox to be uninstalled. Had to download from Oracle's site. Don't waste your time downloading this.
I love Virutalbox-4.3 but not this virtualbox-guest-additions-iso - I need the additions iso for the 4.3 but if I install the iso the 4.3 is removed. HELLO WHO DECIDED TO BE STUPID!!! I manually found the iso on download.virtualbox.org/virtualbox/
Install this on the virtual OS. From Virtual Box menu "Devices" within virtual OS. Choose "Insert Guest Additions CD Image". This will auto-resize the virtual OS window, which is very helpful, and allow use of a shared folder which is also very helpful!
