Bug#1109469: Regression in apt 3.0

Source: apt
Version: 3.0.3

Hi.

We had this working in apt for years, in apt.conf:

Acquire::https::some.host::SslCert
"pkcs11:token=sometoken;object-type=cert;object=someobject;pin-source=file:/dev/null";
Acquire::https::some.host::SslKey
"pkcs11:token=sometoken;object-type=private;object=someobject;pin-source=file:/dev/null";

Where sometoken refers to an access mechanism pkcs11 understands and
someobject identifies the actual credentials (cert and key under the
same name, but differentiated via the type).  The relevant credential
is hardware-backed, so just giving a filename wouldn't work.

This broke with apt 3.0 - probably with 2.9.19, but I didn't cross-check.

Are you aware of any way to achieve this with current apt? Could
support for such a configuration be added back?

Kind regards,
Sven
