Public bug reported: Binary package hint: ubiquity
>From https://lists.ubuntu.com/archives/ubuntu- bugsquad/2011-April/003176.html 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. ** Affects: ubiquity (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/762636 Title: Ubuntu installer kills LUKS partitions without warning -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
