Internal GPG provider fails on Ubuntu Cloud repos

[Grimm75]

Detailed Description

When trying to update mirror 'deb http://ubuntu-cloud.archive.canonical.com/ubuntu/ xenial-updates/pike main' using internel gpg provider, aptly fails with:

$ /usr/bin/aptly mirror update pike-xenial Downloading http://ubuntu-cloud.archive.canonical.com/ubuntu/dists/xenial-updates/pike/InRelease... Downloading http://ubuntu-cloud.archive.canonical.com/ubuntu/dists/xenial-updates/pike/Release... Downloading http://ubuntu-cloud.archive.canonical.com/ubuntu/dists/xenial-updates/pike/Release.gpg... ERROR: unable to update: failed to verify detached signature: EOF

after switching to external gpg provider, everything works fine.

Context

Problem is 100% reproducible and affects all repos on ubuntu-cloud.
Their gpg pubkey can be found here: http://keyserver.ubuntu.com/pks/lookup?search=0x5EDB1B62EC4926EA&op=vindex

Possible Implementation

Your Environment

aptly 1.3.0 @ Debian Stretch

Looks like detached signature is not in armor format, we don't support it yet.

Should be fixed starting with nightly build aptly_1.3.0+40+gec57d17

That nightly build doesn't exist when using deb http://repo.aptly.info/ nightly main. Is it available elsewhere?
