Public bug reported:
APT currently launches dpkg in the same environment as it is launched in
leaking all sorts of environment variables to it, only overriding PATH
with a sensible default.
This is suboptimal, apt should clean the environment more thoroughly or
populate a clean environment from scratch.
Questions to answer:
* Perhaps it can reuse systemd or sudo or pam mechanisms?
* If not, what can we copy/pass-through? e.g. TERM needs to be kept the same.
* What to do about hooks
* umask(022) before executing dpkg (anything?), also need correct umask for
lists for sure.
** Affects: apt (Ubuntu)
Importance: Medium
Status: Triaged

Importance: Undecided => Medium
