Public bug reported: This is related to a bug introduced by Microsoft adding a hint of the key containing the Microsoft account to which the user backed up the key, causing BitLocker partitions with keys backed up in newer Windows versions unable to be unlocked, which was fixed in cryptsetup 2.7.3 .
Links to the original bug and fix: https://gitlab.com/cryptsetup/cryptsetup/-/issues/886 https://gitlab.com/cryptsetup/cryptsetup/-/merge_requests/652 As Ubuntu 24.04's cryptsetup is based on 2.7.0 (and 24.10's based on 2.7.2), I can't unlock my BitLocker drive on my dual boot PC, which is somewhat inconvenient. I think that it would be good if the fix (only involving a little change, 7 lines of code) is backported in some future updates, but I'm new here and don't know if this is legitimate, so forgive me if this sounds unreasonable. ** Affects: cryptsetup (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/2107771 Title: Unable to unlock BitLocker drives on new Windows versions with keys backed up to Microsoft account To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/2107771/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
