Using external gpg provider during mirror create possible regression.

Detailed Description

Step to reproduce :

Using this Dockerfile

ARG TAG_BASE=latest
ARG DEBIAN_CODENAME='buster'

FROM debian:${DEBIAN_CODENAME}-slim as dck_aptly_base

LABEL description="Docker Aptly Base Image"

COPY /src/docker-entrypoint.sh /

ENTRYPOINT ["/docker-entrypoint.sh"]
CMD ["/usr/bin/aptly"]

Then build with :

docker build --build-arg TAG_BASE=building -t dck_aptly_base:building_tmp -f /path/to/docker/file/Dockerfile /path/to/source/of/dck_aptly

When run :

Context

• Working with 1.4.0.
• broken in aptly version: '1.4.0+179+g0a179886' using external provider
  -> working using : -gpg-provider=internal additionnal parameter
  -> doesn't work using : -gpg-provider=gpg or -gpg-provider=gpg2 additionnal parameter

default is like using -gpg-provider=gpg parameter

Your Environment

debian buster
podman 3.0.1 or docker in rootless
using overlayfs
aptly version: '1.4.0+179+g0a179886'

[itcsoft54]

In add after some other tests, it's work with Version: 1.4.0+49+gc43d31f but not with Version: 1.4.0+162+gc46f12f0

[itcsoft54]

Since Version: 1.4.0+162+gc46f12f0, aptly seems to make some thing that is incompatible with driver OverlayFS in rootless mode.
Changing to VFS is a workaround.
