Can't findLinux guest additions installer

Postby RadlyEel » 22. Jul 2019, 22:26

I'm failing miserably to get Guest Additions installed on my Linux guest.

I have VirtualBox 6.0.10 r132072 (Qt5.6.3) running on my Mac 10.14.5; the guest is Ubuntu Server 18.04, with no GUI--it's all CLI. When I mount the Guest Additions in the virtual optical drive, I can't find it in my directory. I've run "ls" on /dev/cdrom, /dev/dvd, /media, /mnt; none of them have any content. There is /dev/disk/by-label/VBox_GAs_6.0.10, which itself is a link to /dev/sr0, which is empty. (When I "remove the disk from the virtual drive", that link disappears. I get exactly the same behavior whether I use the ISO included in the VirtualBox app bundle or the one I downloaded from https://download.virtualbox.org/virtual ... 6.0.10.iso.

I'd love some guidance as to what I might be doing wrong; any suggestions would be appreciated.

That doesn't seem primarily a VirtualBox question, but "How do I find things on my Linux" question, you may have better luck if you searched an Ubuntu forum. In any event, I'm moving it to the "Linux Guests" area from the "OSX Hosts" area.

What exactly are you going to use the GAs for then?

That's where I would expect to find it too...

I wouldn't expect the behavior to be different, it's the same exact action.

In Linux /dev/sr0 is the device file the Linux kernel uses to access the CD-ROM drive. In order to access the contents of the disk you need to mount it into the filesystem. From the command line this wil be:

mount -t iso9660 /dev/sr0 /mnt

Wait a minute... there's no auto-mount, just because it's the server?

No idea, it was just a helpful suggestion :). Obviously if it is auto-mounted it would most likely appear somewhere under /media. The 'df' command would give the definitive answer!
