After disabling Absolute via the Windows WMI PowerShell command, I successfully installed Ubuntu 26.04 Snapshot 3 in TPM-FDE mode, and even the Clear TPM via firmware option in the settings GUI worked perfectly.
But here is the problem: the way to disable Absolyte on HP EliteBook, ProBook, and ZBook is hard and not always acceptable. 1. We need a live Windows or Windows PE to use WMI commands in PowerShell. 2. In old models like the HP EliteBook 860 G11 and older, we can use the "Disable" command. But in the newer HP EliteBook 8 G1i 16 inch Notebook AI PC, there is only one option to use "Permanent Disable". And it is unacceptable, since "Permanent Disable" is irreversible, to re-enable Absolute, we must replace the motherboard in service center. Since all the mentioned HP corporate laptop models are Ubuntu certified, maybe Canonical can ask HP to add the Disable Absolute option in UEFI firmware settings, like it does DELl and Lenovo? Based on the successful setup, I think we can close this Bug and start thinking about the Absolute issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2125409 Title: BootGuard ACM not forced → TPM FDE disabled in Ubuntu 25.10 installer To manage notifications about this bug go to: https://bugs.launchpad.net/snapd/+bug/2125409/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
