Bug#928555: upgrade to buster from stretch suggests to remove bridge-utils

Package: upgrade-reports

Version: buster

My system has a bridge interface configured in /etc/network/interfaces.
I upgraded from stretch to buster.  After the successful upgrade in
the list of packages to be auto-removed is bridge-utils.

"The following packages were automatically installed and are no longer required:
  bridge-utils..."

After running `sudo apt-get dist-upgrade` and a subsequent restart,
the host was missing its bridge interfaces.

Manual installation of bridge-utils fixed the network interfaces.

I suppose bridge-utils did not have any dependencies which was why it
was auto-removed but this is an important package since loss of
connectivity can occur if upgrading remotely.

Thank you,
