I've just come across this one myself... again an NEC CDROM though this time in a Laptop ( a Philips Freevents model. ) Since changing the CDROM is not an option for me, and I don't have a USB CDROM drive handy, I came up with this workaround:
When the message appears the first time: Ctrl-Alt-F2 to get another console. chroot /target vi /etc/apt/sources.list ( comment out the CDROM line by inserting a # at the start, save and quit. ) apt-cdrom add Ctrl-Alt-F1 to get back to the installed and press Enter. ( This is with the alternate install CDROM. ) The message appeared at least once more during the install, but repeating the above got past it. Also, at one point I got a message that selecting and installing failed - again I repeated the above, and selected to repeat the step from the menu. After all of that, I had a working system! Although this seems to be related to NEC CDROM drives, it appears to be a bug since the drive itself works. Ideally someone needs to find out what the root cause is.... -- Alpha-5 alternate installer fails https://bugs.launchpad.net/bugs/270461 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
