I am quite new to Linux. So far I used Ubuntu for a few months. Now after I installed Linux Mint 18 on VirtualBox, and tried to install VirtualBox Guest Additions into it, the installer says that it's already installed from another source and I have to remove it to install the new one.

I know I can continue with the current version, but how do I remove it? What packages need to be uninstalled and what conf filed need to be edited?

170 views, no answers. I've tried the various methods suggested on Mint and Ubuntu's forum. All managed to remove (most of) the pre-installed version of guest additions. However, on reboot before or after installing the correct version of the guest additions for the actual version of virtualbox I use, just end up with a black screen (cinnamon) or unresponsive KDE screen with no widgets.

The only solution I've found is to download a version of it from OS Boxes, which is built without guest additions pre-installed:


If you trust them! Searching their name didn't flag up any issues, though. The downside is, they're pre-built disk images, not installation ISOs.


Just run:

sudo apt purge virtualbox*

This will remove all the pre-installed packages that are giving you trouble. Then insert the guest additions image and re-run the autoinstaller, and you should be good to go.
