So you've got the PPA for mkusb and the Google Chrome repository.
Nothing there should be requiring a specific kernel.

So you've got nothing held.

There's all the packages that you've pinned which we also see in the
results of `apt-cache policy`:

Running `apt-rdepends` against each of those packages, there's no
specific kernel required.

That said, I don't think that we're going to find our solution in
pinning or holding. However, as kc2bez [mentioned][1] on the Discourse
forum, there are other possible packaging reasons:

So you should look into that.

Also, is there a new kernel listed when you run `apt list --upgradable`?

Oh, and we should probably pick one or the other place to discuss this
as it will otherwise be really difficult for anyone else to follow the
conversation.
