Any help and guidance appreciated

The Extension Pack version should always match the Virtualbox version. If you're installing the 6.1.10 EP, you should already be running Virtualbox 6.1.10.

Additionally, be sure the Extension Pack download is not in a folder that has weird permissions.

I don't know that one. It's probably better to ask a question in a new topic (after web-searching the error with 'site:forums.virtualbox.org' added to your search terms) when you get an error.

When you change Virtualbox versions, uninstall the existing Extension Pack first. Then install the correct Extension Pack after Virtualbox is installed and working.

Do i need to uninstall current version to upgrade ?

That one I don't know, I am a Windows guys and have little experience on a Linux PC.

That said, on Windows hosts:

Upgrading within a major version, like 6.1.8 to 6.1.10, it's OK to just run the new installer over the top of the older version.

Upgrading from one major version to another, like 6.0.something to 6.1.something, uninstall Virtualbox and reboot, then install the new version.

Downgrading, always uninstall, reboot, then install.

It should always be safe to uninstall, reboot then install under all situations.

How this goes on Linux hosts might be the same, but I don't know for certain.
