Bug#807012: python3-apt & unattended-upgrades get confused by uppercase pkg

[Alexandre Detiste <alexandre.detiste@gmail.com>]

Package: python3-apt
Version: 1.1.0~beta1
Severity: normal

Hi,

Since the last update of python3-apt to 1.1, unattended-upgrades
is crashing on a package with an uppercase case name.

I do know this package is not policy-compliant;
but still UU / python3-apt should handle this situation
in a more gracefull way than a triple exception.
(and more enterprise-ish stuff may want to use
uppercase package names too)

The .deb is located in a private reprepro repository to enable
fast re-install on my "new win XP laptop of the year".

I'm assigning this first to python3-apt, as
this is where most changes recently happened.

Greets,

Alexandre
