Public bug reported: LUKS boot for encrypted root systems was broken starting with the 3.19.0-49 kernel and all subsequent 3.19 kernels due to an incompatibility between upstream kernel patches not being fully applied and the current vivid cryptsetup version (2:1.6.7-0vanir1~15.04).
This is a documented kernel bug, but Ubuntu has not picked up patches. Current workaround is booting off last working kernel (3.19.0-47-generic). I cannot upgrade to 16 until fix is confirmed as it will force de-install of last current working kernel. ** Affects: libpam-mount (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/1576554 Title: LUKS boot broken since 3.19.0-47+ in 15.04 (upstream patches need backport) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libpam-mount/+bug/1576554/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
