Bug Description

Using virtualbox 7 EFI + secure boot + ubuntu-budgie-installer

Chose the experimental TPM encryption option - press Next which showed he snap recovery instructions.

However the next button doesnt do anything.

Looked at journalctl and saw that there was an unhandled subiquity issue

The client should not have shown you the TPM encryption option in this case (it doesn't look as if the ISO even suports this as an option).

Hi @mwhudson

Interesting! So is this ubuntu-desktop-provision ignoring the return values from subiquity? Should I raise an issue on github?

If a flavour wants to also have experimental TPM support what extra does a flavour need to do? Seed change? livecd-rootfs change?

Hey @fossfreedom,

I'll let @dbungert chime in on the subiquity values issue, but regarding flavour support for TPM FDE, there is some work we would need to do on our side to help create the correct models to support it. We're happy to do this and want to ensure the flavours can take advantage of this feature, but currently we're rather resource constrained on ensuring we have everything in place to broaden our hardware compatibility and deal with issues raised in testing. I worry broadening the matrix of potential scenarios would be unwise at this stage.

I think flavour support is something we need to build into our roadmap going into 24.04 LTS once we're closer to being able to remove the 'experimental' flag on the feature and not something we'd be able to provide for mantic. After release we can coordinate more on what's needed on both sides.

It was in this very narrow case and was showing the TPMFDE checkbox unconditionally. That's fixed though on the Desktop dailies since beta.

Please confirm that you have the latest ubuntu-desktop-provision. I know there was a hiccup there as we were picking a plan for source code branches but I think that's sorted out now. If that's still happening then I think that's a ubuntu-desktop-provision discussion.

the above is the current version that dependabot has updated our installer. I promoted that version before testing.
