Missing CDRom on Ubuntu Server install inside a Virtual Box VM on Windows 10 Pro host

cn flag

I have just downloaded Ubuntu Server from Ubuntu website.

I have installed Ubuntu Server inside a Virtual Box VM on a Windows 10 Pro Host (This host does NOT have a physical CDRom drive)

I have gone to install the Virtual Box Guest Additions but there is no virtual CDRom.

I tried various different tutorials with sudo around...

mkdir /media/cdrom
mount /dev/sr0 /media/cdrom
cd /media/cdrom
sh VBoxLinuxAdditions.run

however the CDRom was either not created or was created inside the media folder but I could not access it as it kept saying I did not have permission.

Can someone tell me how to create a virtual CDRom so I can install the Virtual Box Guest Additions.

I have wiped the previous tries of VM, so now I just have a vanilla install of Server ready to start again. Thanks

You mention Ubuntu Server, but you weren't clear as to which Ubuntu Server product (Ubuntu Server itself, or the *flavor* of Ubuntu Core Server), nor what release of that product.. Please be specific. The CDROM may refer to the installation media; but your description reads more as a HOST problem (ie. windows 10 configuration issue of virtualbox with your *unstated* Ubuntu product in the VM)

I download Ubuntu Server 23.04 from https://ubuntu.com/download/server Ubuntu Desktop 22.04.2 LTS installs fine in Virtual Box and I can see the virtual cdrom drive ok and install VB guest additions.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
