I have successfully used lubuntu-12.10-alternate-amd64.iso to PXE network install a server. But so far, I have not been able to get the desktop login installed regardless what I put in in the preseed file:
tasksel tasksel/first multiselect lubuntu-desktop
d-i pkgsel/include string lubuntu-desktop
Neither triggered a desktop UI install. The logs in the
/var/log/installer subdirectory do not give me any clue either.
I have got around this "issue" by running a
preseed/late_command or use the iso's content in conjunction with a local repository mirror.
BTW, I have noticed that the
Packages.gz in the iso's
universe/debian-installer/binary-amd64 doesn't have any content. Replacing it with the one in the
universe/binary-amd64 and adding a Release file doesn't result a graphical UI install either. How can I "fix" the iso's content so that I can use it for a desktop install with both a burned CD and PXE network boot?
