We want the firmware updater and security center pointing to edge too.
The model only allow to select it, but we need to invoke them by
default in snap prepare-image
To get 25.10 Desktop ISOs with TPMFDE bits, we need matching pc-kernel
and snapd otherwise we get errors like so when running
`snap prepare-image`:
WARNING: the kernel for the specified UC20+ model does not carry
assertion max formats information, assuming possibly incorrectly the
kernel revision can use the same formats as snapd
error: snapd 2.68+ is not compatible with a kernel containing snapd
prior to 2.68
Use the "dangerous" model, which allows overriding the channel, and pick
up the matching pc-kernel which is not yet on 25.10/stable, where the
non-dangerous model would expect to find it.
This model intentionally uses pc-kernel from a branch, for components
testing purposes. We'll have to update this again before release when
the desired pc-kernel is on a stable channel.
This reverts commit c4e69348aed2e89bdef0187afe79da18d855eb8c as
the more debugging is needed for autopkgtest failures and is
therefore blocking apparmor fixes for cloud images.
