apt-mirror2

apt-mirror2 is the Python/asyncio reimplementation of the apt-mirror developed as drop-in replacement for the latest.
This project should be suitable as general apt-mirror replacement.

One of the main advantages of the apt-mirror2 over the apt-mirror - you should never got broken mirror in case apt-mirror2 returns 0 exit code. This is ensured by data integrity checks at all stages of mirroring.

# Let's work in the home folder
cd

# Create virtualenv
virtualenv ~/venv/apt-mirror2
source ~/venv/apt-mirror2/bin/activate

# Clone apt-mirror2 source code
git clone https://gitlab.com/apt-mirror2/apt-mirror2
cd apt-mirror2

# Install requirements
pip install -r requirements.txt

# Install apt-mirror2 into virtualenv
python setup.py install

usage: apt-mirror [-h] [--version] [configfile]

positional arguments:
  configfile  Path to config file. Default /etc/apt/mirror.list

apt-mirror compatibility

Most of apt-mirror configuration directives are supported.
As of now proxy for FTP repositories is not supported.

File lists (ALL, NEW, MD5, SHA256, SHA512) are not written by default, but you can enable them with the write_file_lists option.

In addition there are some enhancements available:

• Repositories without MD5 hashsums are correctly mirrored
• Old index files are properly cleaned and don't produces errors in mirror processing
• Standard source.list [ arch=arch1,arch2 ] can be used to specify multiple repository architectures for mirroring.
• multiple codenames (or flat folders) can be specified using comma as delimiter.
• mirror_path URL PATH option may be used to specify PATH to use for saving mirror files instead of path that is generated from URL.
• Additional configuration is loaded from the *.list files in the directory named same as configfile with the .d suffix. Eg /etc/apt/mirror.list.d/*.list.
• Rate limit is enforced for overall download rate.
• Slow download rate protection is enabled by default and can be configured via mirror.list.
• Non-zero exit code is returned if some of required files were not downloaded due to network or server errors or no repositories were configured.
• HTTP user agent can be configured via user_agent configuration.
• Configuration variables are exposed to postmirror_script.
• by-hash list option can be used to control whether Acquire-By-Hash Release option should be respected or enforced.
• mirror wipe protection is available and configurable via wipe_size_ratio and wipe_count_ratio settings.
• per-repository log files are available in the var_path folder
• dists folder is almost atomicaly replaced using move instead of copy/link
• native Prometheus metrics are supported
