I can confirm I had this same issue with multiple different versions of Ubuntu that I was trying to install via a USB stick created with Unetbootin. I had previously been in the habit of rewriting a USB thumb drive with different bootable images without cleaning it first. When I started wiping the USB thumb drive between loading it with an iso via unetbootin, everything started working.
I think this could be considered a bug in unetbootin. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/658865 Title: Install from USB fails: "An attempt to configure apt to install additional packages from the CD failed" To manage notifications about this bug go to: https://bugs.launchpad.net/estobuntu/+bug/658865/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
