Description:

debpkgr 1.1.0

debpkgr
Pure Python implementation of Debian/Ubuntu packaging and repository utilities.
The allows one to perform various Debian-specific operations on
non-Debian systems, in the absence of typical system-provided
utilities (e.g. apt).

Example

Inspect Package
from debpkgr.debpkg import DebPkg

pkg = DebPkg.from_file('/path/to/foo.deb')

print(pkg.name)
print(pkg.nevra)
print(pkg.md5sum)
print(pkg.package)

Create Repo
from debpkgr.aptrepo import create_repo

name = 'test_repo_foo'
arches = ['amd64', 'i386']
description = 'Apt repository for Test Repo Foo'

files = []
for root, _, fl in os.walk(temp_dir):
for f in fl:
if f.endswith('.deb'):
files.append(os.path.join(root, f))

repo = create_repo(self.new_repo_dir, files, name=name,
arches=arches, desc=description)

Signature Support
It is possible to sign the repository metadata using a wrapper script /
executable around GPG or another GPG-signing facility (like a [Hardware Security Module](https://en.wikipedia.org/wiki/Hardware_security_module).
To do so, you will need to pass a SignOptions object to the lower-level
AptRepo class as the gpg_sign_options argument:
gpg_sign_options = SignOptions(cmd="/usr/local/bin/sign.sh",
key_id="45BA0816")
repo = AptRepo(repo_dir, repo_name,
gpg_sign_options=gpg_sign_options)
The supplied sign command has to be an executable.
It will be supplied the path to a Release file to be signed, and is
expected to produce a file named Release.gpg in the same directory as the
Release file.
Additionally, the sign command will be passed the following environment
variables:

GPG_CMD
GPG_KEY_ID (if specified in the configuration file)
GPG_REPOSITORY_NAME
GPG_DIST

The sign command may decide on a key ID to use, based on the repository name
or the dist that is being signed.
A minimal sign command using GPG could be:
#!/bin/bash -e

KEYID=${GPG_KEY_ID:-45BA0816}

gpg --homedir /var/lib/debpkgr/gpg-home \
--detach-sign --default-key $KEYID \
--armor --output ${1}.gpg ${1}
You could import your password-less GPG keys like this:
mkdir /var/lib/debpkgr/gpg-home
chmod 0700 /var/lib/debpkgr/gpg-home
gpg --homedir /var/lib/debpkgr/gpg-home --import <path-to-secret-keys>
