Dockerized PPA downloader for apt installs.

Since Ubuntu 20.04,snap is the new package management standard for Ubuntu, over the old-schoolapt. Unlikeapt,snap packages embark all dependencies into a single file to be easily deployed (packages are self-contained).

However, it requires tricky configuration for offline infrastructures. For example, in Ubuntu 22.04, Chromium is not in the officialapt mirror anymore, which is either installable throughsnap orthrough the install of a PPA (Personal Packages Archives). This is not possible on "on-the-edge" infrastructures because it requires Internet.

This repositories allows to easily retrieve files from a specific PPA for Ubuntu systems, for packages to be downloadable through the traditionalapt command.

It is useful for large-clients infrastructures. Another reason might besnap is not allowed to be used by your organization.

Note : If you are allowed to usesnap and only have 1 package to download, you might considerdownloading it manually.

1. Copy and edit the.env file with your own configuration

   cp .env.example .env

2. Run themirror container :

   docker-compose builddocker-compose run mirror

Tips: We recommend you downloading the mirror froma cloud provider and then transfer files to your computer.

1. Check your mirroring succeeded typingdu -sh ./mirror to check the folder volume. Size varies depending on the PPA downloaded.

2. Run the server :

   docker-compose up -d server

   Server will run onlocalhost:8080

1. Add the GPG keys of the downloaded PPAs

   cat ./mirror/ppa.launchpadcontent.net/savoury1/ffmpeg4/ubuntu/savoury1-ffmpeg4.pgp| gpg --no-default-keyring --keyring gnupg-ring:/etc/apt/trusted.gpg.d/savoury1-ffmpeg4.pgp --import -cat ./mirror/ppa.launchpadcontent.net/savoury1/chromium/ubuntu/savoury1-chromium.pgp| gpg --no-default-keyring --keyring gnupg-ring:/etc/apt/trusted.gpg.d/savoury1-chromium.pgp --import -

2. Make your Ubuntu computer point to your mirror by creating a/etc/apt/source.list.d/ppa-mirror.list file as follow :

   # For default example with ppa.launchpadcontent.net/savoury1 on Ubuntu Jammy (amd64)deb [arch=amd64] http://localhost:8080/ppa.launchpadcontent.net/savoury1/ffmpeg4/ubuntu jammy maindeb [arch=amd64] http://localhost:8080/ppa.launchpadcontent.net/savoury1/chromium/ubuntu jammy main

👉 Feel free to add a reverse proxy or update thenginx configuration file to secure the mirror with SSL/TLS
👉 Feel free to sendpull requests as well !
