[Bug 1651923] Re: apt https method decodes redirect locations and sends them to the destination undecoded.

[Julian Andres Klode]

No regression. The quick hack we can try for now is parsing the URI we
get and then encoding the local part. This is what I'm aiming for this
month and it will fix this issue.

The correct fix requires restructuring the whole acquire system to not
decode URIs in redirect requests and encode given URIs before sending
the request. Since APT is freezing down for Debian stretch soon, that's
likely not going to happen anytime soon (that targets apt 1.5, so 17.10
or 18.04).
