A quick bit of testing shows that this regressed between ubuntu-15.04-server-amd64.iso and ubuntu-15.10-server-amd64.iso . So:
WORKS: ubuntu-14.04.4-server-amd64.iso WORKS: ubuntu-15.04-server-amd64.iso FAILS: ubuntu-15.10-server-amd64.iso FAILS: xenial-server-amd64-daily-20160411.2.iso Thats good, because it means if the regression was in syslinux, then it was between 3:6.03+dfsg-5ubuntu1 and 3:6.03+dfsg-8ubuntu2 (there was a major version bump in syslinux between trusty and but it still seems to work in vivid. so that is good): $ rmadison syslinux syslinux | 2:4.05+dfsg-2 | precise | source, amd64, i386 syslinux | 3:4.05+dfsg-6+deb8u1 | trusty | source, amd64, i386 syslinux | 3:6.03+dfsg-5ubuntu1 | vivid | source, amd64, i386 syslinux | 3:6.03+dfsg-8ubuntu2 | wily | source, amd64, i386 syslinux | 3:6.03+dfsg-11ubuntu1 | xenial | source, amd64, i386 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1505839 Title: Unable to install from text mode interface To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1505839/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
