Public bug reported:

Reporting a bug as suggested in https://answers.launchpad.net/ubuntu/+question/288658
I attached Vagrantfile that reproduces the problem in which I try to add the following repositories to apt:

deb https://FOO@BAR:PASS@not-existing-domain.com/xyz precise non-free
deb https://FOO%40BAR:PASS@not-existing-domain.com/xyz precise non-free

---

For both URLs the error message on Ubuntu 12.04 is the same:

Failed to fetch https://domain.com/xyz/dists/precise/non-free/binary-
amd64/Packages  Couldn't resolve host 'BAR'

$ lsb_release -a
Distributor ID:	Ubuntu
Description:	Ubuntu 12.04.5 LTS
Release:	12.04
Codename:	precise
$ apt-get --version
apt 0.8.16~exp12ubuntu10.26 for amd64 compiled on Aug  5 2015 19:06:57

---

On Ubuntu 14.04 the URL is parsed correctly as in both cases the
following error message is printed:

Failed to fetch https://not-existing-domain.com/xyz/dists/precise/non-
free/binary-i386/Packages  Could not resolve host: not-existing-
domain.com

$ lsb_release -a
Distributor ID:	Ubuntu
Description:	Ubuntu 14.04.4 LTS
Release:	14.04
Codename:	trusty
$ apt-get --version
apt 1.0.1ubuntu2 for amd64 compiled on Jan 12 2016 20:13:58

For security reasons I prefer not to disclose the real repository URL,
but it works on Ubuntu 14.04 and doesn't work on 12.04.
