Severity: normal

Building a ubuntu karmic or lucid iso

I have this in chroot:

# $LH_LINUX_FLAVOURS: set kernel flavour to use
# (Default: autodetected)
LH_LINUX_FLAVOURS="generic"

When having this settings I get this error:

# $LH_DEBIAN_INSTALLER: set debian-installer
# (Default: disabled)
LH_DEBIAN_INSTALLER="enabled"

# $LH_DEBIAN_INSTALLER_DISTRIBUTION: set debian-installer suite
# (Default: empty)
LH_DEBIAN_INSTALLER_DISTRIBUTION="lucid"

# $LH_DEBIAN_INSTALLER_PRESEEDFILE: set debian-installer preseed filename/url
# (Default: )
LH_DEBIAN_INSTALLER_PRESEEDFILE=""

# $LH_DEBIAN_INSTALLER_GUI: toggle use of GUI debian-installer
# (Default: enabled)
LH_DEBIAN_INSTALLER_GUI="disabled"

If I have this one disabled:
# $LH_DEBIAN_INSTALLER: set debian-installer
# (Default: disabled)
LH_DEBIAN_INSTALLER="disabled"

I don't get that error.
