How do I bypass "No common CD-ROM drive was detected" error during custom image install?

Linode Staff

I'm trying to install a Buster alpha-3 netinst image on my Linode but I keep receiving:
No common CD-ROM drive was detected

The installer fails with the error at the stage of mounting the CD. When I start a shell in the installer, there are also no drives or cd devices listed under /dev.

How can I skip the requirement for a CD-ROM?

Thank you for saving us a few keystrokes, [@Woet] (/community/user/Woet)!

I'm answering my own question here since it might be of use to others.

The main problem is that the Linode documentation on installing a custom distribution is incomplete.

(https://www.linode.com/docs/tools-reference/custom-kernels-distros/install-a-custom-distribution-on-a-linode/)

In addition to the steps documented in the link, I had to:

  • The "Installer" profile has to set the "VM Mode" to "Full-virtualization". With this the disk devices are now seen in the /dev directory. I don't understand why this is necessary.

  • After booting to the installer, start a shell and mount /dev/sdb1 to /cdrom. Again it's not clear to me why this is necessary since the Debian installer will do this by default when installing to real hardware.

After these two additions I can boot and proceed with the install.
