The workaround of copying ldlinux.c32 does not work. The problem as documented upstream in http://www.syslinux.org/archives/2015-September/024305.html still exists; see below my configuration*.
What happens after copying ldlinux.c32 to /tftpboot: - the system attempts to execute the default boot option from the pxelinux.cfg/default menu, no matter what I type at the boot prompt - if I make booting a kernel over http the default option, boot fails with the message: "Loading http:////nl.archive.ubuntu.com/ubuntu/dists/xenial/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/linux... failed: No such file or directory" (no matter what I type at the boot prompt) What happens after removing /tftpboot/ldlinux.c32 and copying gpxeboot.0 from an ubuntu 14.04 machine: - system boots as expected. *) I'm using the following config: Ubuntu release: Description: Ubuntu 16.04.2 LTS Release: 16.04 pxelinux: Installed: 3:6.03+dfsg-11ubuntu1 - dnsmasq: dhcp-boot=gpxelinux.0 enable-tftp tftp-root=/tftpboot log-dhcp dhcp-range=10.38.18.10,10.38.18.100 - /tftpboot/gpxelinux.0 copied from /usr/lib/PXELINUX/gpxelinux.0 - /tftpboot/pxelinux.cfg/default: DEFAULT l LABEL l localboot 0 prompt 1 timeout 1200 LABEL xenial64 kernel http://nl.archive.ubuntu.com/ubuntu/dists/xenial/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/linux append initrd=http://nl.archive.ubuntu.com/ubuntu/dists/xenial/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/initrd.gz ramdisk_size=16432 root=/dev/rd/0 rw console-setup/ask_detect=false console-setup/layoutcode=us debian-installer/locale=en_US.UTF-8 debconf/priority=critical -- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577554 Title: pxelinux.0 - Failed to load ldlinux.c32 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/syslinux/+bug/1577554/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
