Bug Description

mike@mike-think:~$ do-release-upgrade -c
Checking for a new Ubuntu release
Failed to connect to https://changelogs.ubuntu.com/meta-release-lts. Check your Internet connection or proxy settings
No new release found.

This machine does not need a proxy to get to the internet.

If I go into web browser and open the link I get the page.

host command does find the host:

mike@mike-think:~$ host changelogs.ubuntu.com
changelogs.ubuntu.com has address 91.189.95.15
changelogs.ubuntu.com has IPv6 address 2001:67c:1560:8008::11

dig also find the host

mike@mike-think:~$ dig changelogs.ubuntu.com

There is 02proxy

Acquire::http { Proxy "http://cache:3142"; };

It is apt-cacher-ng running 16.04.

I found something on the net that talk about adding
passThroughPattern: ^changelogs.ubuntu.com:443$

This fixed the problem for me.

Ubuntu now uses https to connect to changelogs.ubuntu.com (LP: #1744318)

When using ACNG, this causes two things to break:

do-release-upgrade tries to download from changelogs.ubuntu.com via https, and fails

The daily release-upgrade-motd fails to connect to changelogs.ubuntu.com, and generates the error message "Failed to connect to https://changelogs.ubuntu.com/meta-release-lts. Check your Internet connection or proxy settings"

As proposed in LP: #1771914, it would be good to add this setting to the default acng.conf on Ubuntu:
PassThroughPattern: ^changelogs.ubuntu.com:443$

It seems to have been fixed in Ubuntu 20.04:

----
/etc/apt-cacher-ng/acng.conf

# Default: ^(bugs\.debian\.org|changelogs\.ubuntu\.com):443$
