Bug#868345: Progress should be shown when using apt-transport-https

["Jason Self" <jason@bluehome.net>]

Package: apt-transport-https
Version: 1.0.1
Severity: minor

I've noticed that visible download progress is not shown in apt (sudo apt 
full-upgrade for example) when using a repository over HTTPS (after 
installing apt-transport-https.)

The download is successful but the indicator remains at 0% (or at 
whatever percent it was when it started downloading from the HTTPS repo, 
in cases where the upgrade process had first downloaded packages from 
other repos before moving on to the HTTPS one.)

The usual things like rate of speed and time remaining do not get 
displayed, resulting in the appearance that it's hung. Examining activity 
does show it's indeed downloading though, just not displaying anything.

To reproduce it:
Install apt-transport-https.
Configure the package manager to use a repo over HTTPS.
Install a package.
Watch as no progress is shown but it is downloaded successfully and the 
normal installation process happens.
Later, remove the package & do apt-get clean so that .deb so that it has 
to be downloaded again.
Edit sources.list and replace https with http and install the package 
again.
Notice that things like rate of speed and time remaining are displayed, 
while they were not previously. The only difference being the use of http 
vs https.
