I wanted to try Lubuntu but can't install guest additions

I get this error "can't find guest additions try installing them manually." Manually? What does that mean?

Why can't it find the guest addition it's right there in the optical drive. I see the files in the directory I right click on the .sh file, open with QTerminal nothing happens.

I downloaded a dab file with the guest additions installed. Windows host doesn't know what to do with a dab file. I can't connect linux to the internet or share a file without guest edition installed.

I've sudo this and apt get that and nothing but errors.

Why is it you can't do anything simple with Linux? What am I doing wrong other than barely understanding how to use Linux.

Solution 1:

You haven't stated what release of Lubuntu you're using, so I've just used my own system.

I'd suggest opening the package manager (Muon) and doing a search for "virtualbox" which presented me with this screen

You'll note a number of virtualbox packages (extensions) that can be added (that I don't have installed). The screen shows the results of my search.

Given I'm unsure what release you're using, nor what you want to do with it I'll assume you know which ones you're after.

Sorry I don't know what a dab file is.
