<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /></head><body style='font-size: 10pt; font-family: Verdana,Geneva,sans-serif'> Hi all, I am facing a weird situation where an automated Ubuntu installation d-i seems to be freezing after Grub has finished installing. The last message that is shown in terminal 4 that seems to be some kind of error is: main-menu: WARNING ***: Internal error! Cannot find "debian-installer/main-menu doesn't exist" in menu. On the main screen is just a blank purple background, no message or popup of any kind. I've done a lot of searching on Google and have found one previous report of this with no answer that I could find. I've also enabled debconf debug and the output doesn't seem to point towards any particular cause of this issue. This happens if the node is installed via biosgrub method. If I install the node via UEFI, this error does not happen. Unfortunately I can't just rely on UEFI though due to this configuration needing to work for multiple different hardware platforms. Any help towards what to start looking at would be greatly appreciated. Thank you! <div> </div> </body></html>
