./VBoxLinuxAdditions.run: Permission Denied

[cephasiii]

When inserting "Guest Additions CD" via the Devices tab, and running the below command, i receive this error:

cephasiii@debian:/media/cdrom0$ sudo ./VBoxLinuxAdditions.run
[sudo] password for cephasiii:
sudo: unable to execute ./VBoxLinuxAdditions.run: Permission denied

Anyone encountering this? I had Debian installed before and didn't have any issues. This seems to be from a recent update of VirtualBox.

Thanks.

Probably because of the mount options of /media/cdrom0. Try

Code: Select all

sh ./VBoxLinuxadditions.sh

.

@frank, thanks for the reply, but no such luck.

Error received:
cephasiii@debian:/media/cdrom0$ sh ./VBoxLinuxAdditions.sh
sh: 0: Can't open ./VBoxLinuxAdditions.sh

Does it work if you copy that file to another location (e.g. your home directory) and start it from there?

cephasiii@debian:/media/cdrom0$ sh ./VBoxLinuxAdditions.sh

You still need to use sudo. " sudo sh ........"

[ogMischiefMeow]

the correct command to run this installation is

Code: Select all

sudo sh ./VBoxLinuxAdditions.run

Obvs you need to change directory to the desired location, if you have an error mounting the drive you can easily download the iso and mount it manually using >download_virtualbox_org/virtualbox< just by choosing your version of VirtualBox. In my case it's >download_virtualbox_org/virtualbox/6.0.4/< meaning >download_virtualbox_org/virtualbox/6.0.4/VBoxGuestAdditions_6.0.4.iso< is my download location.

Wasn't allowed to post links - change all the _ inbetween download, virtualbox, and org. To fullstops!

There are almost no circumstances in which a regular user of VirtualBox will need to manually download the Guest Additions ISO. The matching version of the file is always provided as part of the VirtualBox installation.

The correct procedure to make it available to the guest is "Devices" -> "Insert Guest Additions CD Image..." from the menu when the guest window has focus.
