Dear all, I just sent the email below to ubuntu-bugsquad@xxxxxxxxxxxxxxxxx I did not find another way to report a bug without installing Ubuntu (which am an not about to do). If somebody knows a better way or has Ubuntu installed and can file this directly for the installer package, please feel free. I hope this communicates the problem adequately. Arno --- Subject: Ubuntu installer kills LUKS partitions without warning Hi, first, I don't have Ubuntu and I don't plan on using it. As I did not find another way that allows me to report a serious issue without subscribing to something, I use this venue. Please forward this to the Ubuntu installer development team. The dm-crypt mailing list (archive here: http://dir.gmane.org/gmane.linux.kernel.device-mapper.dm-crypt) has had several reports that the Ubuntu installer creates new LUKS partitions (encrypted partitions) on top of exisiting ones without giving adequate warning and at the same time giving the impression that the existing LUKS partition would be activated. The rather clear warning and verification question asked by the cryptsetup tool seems to get disabled with the "--batch-mode" option. This causes irreversible loss of all data! Nothing (in the cryptographically strong sense) can be done to get the data back! Checking for an existing LUKS partition is easy, it has the magic string 'L','U','K','S, 0xBA, 0xBe at the beginning. It seems this is not checked for, or no additional warning or only inadequate additional warning is given if a pre-exisiting LUKS partition is about to be permanently and irretrivably erased. Please fix the installer ASAP and if you need help doing it right, _ask_! We will be happy to help. Regards, Arno Wagner Maintainer cryptsetup FAQ -- Arno Wagner, Dr. sc. techn., Dipl.
