ubuntu-release-upgrader-core missing a dependency

[Brian Murray]

Test Case
---------
1) Install ubuntu-release-upgrader-core on an 18.04 chroot
2) Edit /etc/update-manager/release-upgrades set Prompt=normal
3) Run 'do-release-upgrade -d'
4) Observe the following

(bionic-amd64)root@impulse:~# do-release-upgrade -d
Checking for a new Ubuntu release
Failed to connect to https://changelogs.ubuntu.com/meta-release-development. Check your Internet connection or proxy settings
Upgrades to the development release are only
available from the latest supported release.

Installing ca-certificates resolves the issue, this was likely caused by the fix for bug 1744318.

I tested this with ubuntu-release-upgrader-core version 1:18.04.27 from bionic-proposed. When installing the updated version of the package both ca-certificates and openssl were installed.

(bionic-amd64)root@impulse:~# apt install ubuntu-release-upgrader-core
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following additional packages will be installed:
  ca-certificates openssl python3-distupgrade
The following NEW packages will be installed:
  ca-certificates openssl
The following packages will be upgraded:
  python3-distupgrade ubuntu-release-upgrader-core

After which I no longer received the error message when trying to upgrade.
