[SOLVED] Guest Additions Linux?

[Berilac]

Running into a slight problem installing Guest Additions on Ubuntu 8.04 guest.
When I try to mount the .iso I get the following error:

Code: Select all

mount: block device /dev/scd0 is write protected, mounting read only

Is there somewhere to alter this setting?

Running VBox3.1 on Ubuntu9.10 Host

I would think that a CD or ISO would normally be mounted as read-only. Does this prevent you from installing the Guest Additions?

Um yes your correct, how to make one look like a right plonker in one easy move. Ask a question before thinking about what your asking, DOH!

Yeah after I have changed dir to /dev and done ls to check contents

Code: Select all

sh ./VBoxLinuxAdditions-and64.run
sh: cant open ./VBoxLinuxAdditions-amd.run

/dev nust be the cdrom cuz I can see it in that directory?

~~edit~~
SOLVED
I was in the wrong dir for my cdrom
Lesson; pay attention to error reported back= cdrom mounted at /media/cdrom0 not /dev
