Error mounting guest additions on Ubuntu 13.04

my Host OS = OSX 10.9

For some reason when I try to automatically add guest additions it defaults to trying to run VBOXADDITIONS_4.2.18 even though I have 4.3.4 installed. I think this might be because I'm using a downloaded/copy of a VM Image hooked up to a server.

Either way, I thought I would be able to circumvent that by manually mounting the proper guest additions.

I made sure to run "sudo apt-get install dkms" before I did any of this also.

I got it to run from VBOXADDITIONS_4.3.4 instead and it completely downloaded. Then when I reset my VM and reopened it my cursor disappears and inside my Files there's a VBOXADDITIONS_4.3.4 icon along the left (i think as a disc? it's under DEVICES with another icon that says computer). Either way, when I click on that it gives me:

Code: Select all

Error mounting /dev/sr0 at /media/MYVMNAME/VBOXADDITIONS_4.3.4_91027: command-line `mount -t "iso9660" -o
"uhelper = udisk2,mode=0400,dmode=0500"
"/dev/sr0" "/media/MYVMNAME/VBOXADDITIONS_4.3.4_91027" exited with non-zero exit status 
32: mount: unknown filesystem type 'iso9660'
Also I'm not entirely sure if I tried mounting it correctly - I went to the device tab in the menu of my running VM (as stated in user manual) but I couldn't find the "Mount CD/DVD-ROM" option it told me to click, so instead I did CD/DVD-ROM > add CD/DVD-ROM and opened the VBoxGuestAdditions.iso for 4.3.4 through there - which then seemed to run the code the same way the automatic way would have done

Clearly something went wrong...
I would download 4.2.18 and just try to get it work from the guest additions it tries to download from default but it doesn't support 10.9 (Mavericks support was added 4.2.20).

Truthfully I don't even fully need guest additions - i'm doing all of this because I just want to make my display size in vm larger (and i've legitimately tried every sudo-solution on the internet: adding an option through xrandr (gave me some sort of gamma not found error, so tried stating --gamma 1:1:1 and it gave me zero value for gamma error), setextradata and controlvm with VBoxManage command, looking for xorg.conf file (which didn't exist on my image, so I'm guessing it was deprecated), etc).

Although ideally I'd like to add guest additions to be able to scroll with my touchpad and what-not but If someone can give me a way to resize my display that works I'll take it also.

First : Are you running this on the guest?
Second : why do you try special attributes? Why not just mounting using the regular : mount /media/cdrom ?
