This is not a bug in cryptsetup; like various others, it's a bug in whatever is mounting the disk without properly unmounting it on logout. Maybe this is gnome-disk-utility?
> Log out of first use and log into second user (switching users would also do) No, because that implies that you want both users to mount the disk simultaneously. That's a recipe for filesystem corruption. ** Package changed: cryptsetup (Ubuntu) => gnome-disk-utility (Ubuntu) -- luks encrypted volumes are not multi-user friendly https://bugs.launchpad.net/bugs/660140 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
