I tested installing Ubuntu server 14.04.2 on a new machine with a new USB stick, and every time it still failed. This time I managed to track down the root cause: the ubuntu-14.04.2-server-amd64.iso contains symbolic links, and these links are lost when the iso image is written to a bootable USB disk as the FAT32 filesystem does not support POSIX links.
The links in question are these (browsing from a loop mounted iso image): install/netboot$ ll yhteensä 7 dr-xr-xr-x 1 root root 2048 tammi 22 14:56 ./ dr-xr-xr-x 1 root root 2048 helmi 18 21:46 ../ lr-xr-xr-x 1 root root 33 tammi 22 14:56 pxelinux.0 -> ubuntu-installer/amd64/pxelinux.0 lr-xr-xr-x 1 root root 35 tammi 22 14:56 pxelinux.cfg -> ubuntu-installer/amd64/pxelinux.cfg/ dr-xr-xr-x 1 root root 2048 tammi 22 14:56 ubuntu-installer/ -r--r--r-- 1 root root 58 tammi 22 14:56 version.info otto@XPS-L322X:~/Lataukset/mnt/install/netboot$ ll ubuntu-installer/amd64/ yhteensä 27792 dr-xr-xr-x 1 root root 2048 tammi 22 14:56 ./ dr-xr-xr-x 1 root root 2048 tammi 22 14:56 ../ dr-xr-xr-x 1 root root 4096 tammi 22 14:56 boot-screens/ -r--r--r-- 1 root root 22073953 tammi 22 14:56 initrd.gz -r--r--r-- 2 root root 6347032 tammi 22 14:56 linux -r--r--r-- 1 root root 26720 tammi 22 14:56 pxelinux.0 dr-xr-xr-x 1 root root 2048 tammi 22 14:56 pxelinux.cfg/ otto@XPS-L322X:~/Lataukset/mnt/install/netboot$ ll ubuntu-installer/amd64/pxelinux.cfg/ yhteensä 4 dr-xr-xr-x 1 root root 2048 tammi 22 14:56 ./ dr-xr-xr-x 1 root root 2048 tammi 22 14:56 ../ lr-xr-xr-x 1 root root 28 tammi 22 14:56 default -> ../boot-screens/syslinux.cfg I fixed it now by copying manually all files that didin't exist due to broken links: cd /media/04A1-26A8/install/netboot/ cp ubuntu-installer/amd64/pxelinux.0 . mkdir pxelinux.cfg cp ubuntu-installer/amd64/boot-screens/syslinux.cfg pxelinux.cfg/default -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1312586 Title: Default 14.04 server installation fails with error 'busybox-intramfs cannot be installed' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1312586/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
