ii base-files 11ubuntu5.1 amd64 Debian base system miscellaneous files
ii curl 7.68.0-1ubuntu2.2 amd64 command line tool for transferring data with URL syntax

 * Are you ready for Kubernetes 1.19? It's nearly here! Try RC3 with
   sudo snap install microk8s --channel=1.19/candidate --classic

   https://microk8s.io/ has docs and details.

Without curl:
$ dpkg -l curl | grep curl
un curl <none> <none> (no description available)

motd-news exits immediately:
ubuntu@focal-motd-news-wget:~$ sudo /etc/update-motd.d/50-motd-news --force
ubuntu@focal-motd-news-wget:~$ echo $?
0

With base-files and motd-news-config from focal-proposed:
ubuntu@focal-motd-news-wget:~$ apt-cache policy base-files motd-news-config
base-files:
  Installed: 11ubuntu5.2
  Candidate: 11ubuntu5.2
  Version table:
 *** 11ubuntu5.2 500
        500 http://br.archive.ubuntu.com/ubuntu focal-proposed/main amd64 Packages
(...)
motd-news-config:
  Installed: 11ubuntu5.2
  Candidate: 11ubuntu5.2
  Version table:
 *** 11ubuntu5.2 500
        500 http://br.archive.ubuntu.com/ubuntu focal-proposed/main amd64 Packages

Still no curl:
$ dpkg -l curl | grep curl
un curl <none> <none> (no description available)
