Bug Description
I've upgraded a server via `do-release-
Focal. It was ENI configured (since Ubuntu 12.04 Precise):
```
auto lo
iface lo inet loopback
# The primary network interface
iface eth0 inet manual
# The primary bridge interface
auto br0
iface br0 inet static
address 10.230.71.10
netmask 255.255.248.0
gateway 10.230.64.1
bridge_ports eth0
dns-nameservers 10.230.64.1
```
and I lost SSH access to the system after the upgrade was completed because bridge-utils was removed during the last upgrade phase:
```Remove obsolete packages?
187 packages are going to be removed.
...
Removing bridge-utils (1.6-2ubuntu1) ...
```
I think the reason was because `bridge-utils` was automatically installed, probably via `libvirt-bin`, but is this correct - a automatically package cleanup happening in an "obsolete removal" phase?
I know it could be a special case where bridge-utils was not manually installed and you are still using ENI instead of netplan, but other people may hit the same problem
