PoC Ubuntu: Package Version History
Example 1: Using the PackageVersionHistory python class
# The below example code showcases how to use this class to check version history for specific source_package_names and distribution_versions
# returns: ( package_name, [list_of_versions] )
In [1]: import package_version_history as p
In [2]: kernel_checker = p.PackageVersionHistory('linux', '20.04')
In [3]: python_checker = p.PackageVersionHistory('python3.8', '20.04')
In [4]: kernel_results = kernel_checker.package_name_and_version_history()
In [5]: python_results = python_checker.package_name_and_version_history()
Seed Data: How to pull all source package names in a target distribution (Need local shell access)
We need local shell access to a system to run some commands to create a text file that contains every remote package source name in the repos on a target distro. The below sequence of commands should create a text file with source_package_names uniqu'd and sorted.
# this will create a text file with the values
# this originally worked on a VM.
grep ^Source /var/lib/apt/lists/*_Packages | awk ' {print $2}' | sort -u > source_packages_remote_ubuntu_2004.default
# this works for me pulling the following:
# ubuntu:latest, ubuntu:22.10, ubuntu:22.04, ubuntu:20.04
docker run ubuntu:latest /bin/bash -c "apt-get update && apt-get install lz4 && lz4cat /var/lib/apt/lists/*_Packages.lz4 | grep ^Source | cut -f 2 -d : | cut -f 2 -d ' ' | sort -u "
it is grepping through information that is stored as follows. Below is an example from the package lvm2
