Ok, more progress. keyctl must be installed otherwise update-initramfs fails and you have to guess why.
And with everything plumbed in, I can't actually enter my passphrase and the machine is unusable. The reason is decrypt_keyctl is not using whatever means is correct for prompting for the passphrase. Before I would get the prompt on the main Ubuntu screen (logo and 5 animated dots). That screen just animates forever. If I switch consoles I do end up on one that says "Caching passphrase for ....:" as what looks like a prompt, but I can't get it to accept anything. In recovery mode the animated ubuntu screen is not present, instead just a text mode. I get a prompt this time, but again can't get it to accept anything. If I switch to the dmesg console, nothing is echoed until I hit return. At that point decrypt_keyctl just says "No key available for this passphrase" against the UUID of each encrypted device and then I am dumped out at the (initramfs) shell. So yeah, using it as things stand is a solution in spirit but in practise leaves you with an unbootable machine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1022815 Title: initramfs should try password against other devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1022815/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
