Title:
  release-upgrade-motd can't update message via apt proxy

Status in update-manager package in Ubuntu:
  Triaged

Bug description:
  I have configured apt proxy in apt.conf.d and apt update and apt
  install can work correctly. However, when I logged in system everyday,
  in the login message, it says:

  Failed to connect to https://changelogs.ubuntu.com/meta-release-lts.
  Check your Internet connection or proxy settings

  After further investigation, I found the the issue is caused in
  package python3-update-manager:

  python3-update-manager: /usr/lib/python3/dist-
  packages/UpdateManager/Core/utils.py

  In the init_proxy function of the python script, it only set a http
  proxy by below code:

  proxy_support = ProxyHandler({"http": proxy})

  after changing the line to add https proxy, it can work:

  proxy_support = ProxyHandler({"http": proxy, "https":proxy})
