Got sick and tired of this bug so figured I'd find out what the cause is. Turns out (for me) because I overwrote multiple versions of Linux using unetbootin, there were multiple apt folders in dist/ on the drive (i.e. yakkety, zesty, etc) so when the 40cdrom script came around, it tried to validate the GPG signature of all the dist/ repos including the non-target dist/ which of course fails so it bubbles up as a failure of the whole installation script. Removing the folder in question made the installation proceed without issues.
PS: Without 40cdrom script, latter part of the installation fails if you have a UEFI system since it won't be able to find the signed grub shim so this approach is not recommended. tl;dr fix: Removing the folder not matching installation CD version from your USB dist/ folder should make it work. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
