ubuntu-server: remove openssh-server (LP: #1974483) ssh-import-id is part of the server-minimal task, which means it and openssh-server are always installed by Subiquity regardless of user choice. Since we can't update the Task headers post release, ensure that openssh-server, openssh-sftp-server, and ssh-import-id are not included in the minimal and full layers by purging them in a dedicated hook. 5 months ago			`#!/bin/bash -ex`
