Public bug reported:
Hello,
The snap packages pc-kernel from ubuntu 22 to 24 are missing firmware
for bluetooth to work properly on dell laptops. The firmware are
available on linux-firmware apt package meaning that both distribution
medium are not aligned.
pc-kernel is required to get tpm full disk encryption so no easy
workaround exists.
