@peat-new After some discussion about the upstream bug, I'm re-opening this as 'New'.
It seems that 'Volume Full' here indeed only refers to the event log filling up and not the entire variable store. The shim debug log was confusing me into thinking it was the full variable store. This could possible be fixed by allowing shim to drive forward in the face of errors, because as mentioned the PCRs are indeed extended just not the event log. Could you possibly verify this theory by disabling TPM support in the firmware and seeing if the device boots via shim with that? ** Changed in: shim-signed (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2061551 Title: Merely booting Ubuntu 24.04 beta live CD breaks BitLocker & booting anything using Shim To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/secureboot-db/+bug/2061551/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
