I thought I was tired or something, but seeing that it happened to somebody else too, I start thinking that the installer's interface sucks ... badly! I assume there is no way to recover the original file system. Ubuntu has most likely overwritten the LUKS header where the pretious salt is being stored. The unencrypted disk most likely looks like random data now. According to the FAQ [1], you can still resort to the dm-crypt mailing-list to get over the five stages of grief. A posteriori, I cannot help wonder why such pretious information isn't kept redundantly. Surely LUKS could have stored the header in 10 random sectors with an easy-to-grep "HERE I AM" banner. Wouldn't this allow users to recover the master-key (and part of the file-system) without compromising security? Cristi. P.S. Could anybody donate 2^256 CPU-seconds? P.S.2. What stage of grief am I in? :D [1] http://code.google.com/p/cryptsetup/wiki/FrequentlyAskedQuestions _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
