[Brian Murray]

What version of python3 are using? I'm unable to recreate this.

bdmurray at clean-bionic-amd64:~$ do-release-upgrade -c
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS develoment release 
set Prompt=normal in /etc/update-manager/release-upgrades.

Title:
  release-upgrade-motd can't update message

Status in update-manager package in Ubuntu:
  Incomplete

Bug description:
  This is a similar bug to the one regarding using a proxy, but I'm NOT
  using a proxy.

  $ lsb_release -rd
  Description:	Ubuntu 18.04.2 LTS

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

  And yet:

  A thing I note: python3-update-manager (Version: 1:18.04.11.9) utils.py url_downloadable doesn't seem to know about https.

  >>> import UpdateManager.Core.utils as umut
  >>> umut.url_downloadable("https://changelogs.ubuntu.com/meta-release-lts", lambda x: print(x))
  url_downloadable: https://changelogs.ubuntu.com/meta-release-lts
  s='https' n='changelogs.ubuntu.com' p='/meta-release-lts' q='' f=''
  False

  
  If I change the line to """ if scheme == "http" or scheme == "https" """:

  >>> import UpdateManager.Core.utils as umut
  >>> umut.url_downloadable("https://changelogs.ubuntu.com/meta-release-lts", lambda x: print(x))
  url_downloadable: https://changelogs.ubuntu.com/meta-release-lts
  s='https' n='changelogs.ubuntu.com' p='/meta-release-lts' q='' f=''
  error from httplib: '<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:847)>'
  False

  
  Dunno if that's helpful at all, but there it is.
