I can confirm that I am seeing this bug in 2018. As I said on the Kubuntu forums:
-- I have attempted to install the Beta-1 version of Kubuntu 18.04: System: Lenovo X220 Laptop, 1TB hard drive, 8GB RAM Medium: Bootable USB, installed from iso using Unetbootin Boot to USB, start Kubuntu, select "Install Kubuntu" from the initial live screen. Options selected to minimum: - English (UK) - no wifi - no 3rd party apps/drivers - guided partitioning (use entire disk, so it's clean) - UK time zone - Set up primary user, password login This starts copying files and get most of the way through the process (the last displayed progress value is 93%) before the installer gets 9% through "Scanning the CD-ROM" and throws up a dialog saying: "An attempt to configure apt to install additional packages from the CD failed." The laptop does not have a CD-ROM drive. The only available action here is "OK" and the crash handler pops up for a moment and the installer is shut down. The system will then not boot from the hard drive - I suspect that writing the boot system is the last thing to be done. The installer should not be looking for the CD-ROM anyway, and even if an error occurs for additional packages, there should be a "skip installation of additional packages" option so that the install can continue. -- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1193725 Title: Install from USB fails: "An attempt to configure apt to install additional packages from the CD failed."
