📝 Multi Package Manager (MPM)

Multi Package Manager (MPM) is a Bash script that enables centralized management of the installation, updating, reinstallation, and removal of selected applications on Debian/Ubuntu-based Linux systems. The script provides a checksum verification mechanism (unfortunately, not all packages officially support this), built-in auto-update (automatic backups during the process), and full support for two languages (Polish/English).

✨ Features

Package Management

• --install — Install package(s)
• --update — Update to the latest version
• --reinstall — Reinstall
• --remove — Remove package(s)
• --check — Check the current version
• --check-self — Check for new versions of the script
• --update-self — Download the latest version of the script from GitHub Releases

Additional script features

• Backups — Automatically saves copies of the previous version of the script in the /old directory (currently, backups are supported only for MPM and install-yubico-authenticator.sh)
• Logging — Logs generated by the script itself are available in the /var/lib/multi_package_manager_config_and_logs/ directory
• 🔤 Dual-language support — Polish / English (Automatic detection of the system language or use of user settings)
• ⚙️ Configurable — basic configuration via the mpm.conf file (I’ll try to expand the functionality of this file in the future)

🔒 Security

• SHA512 verification for: Proton packages
• SHA256 verification for: --update-self
• “Fail-Closed” mode — installation blocked if verification fails for Proton and self-update

🛠 System Requirements

• Distribution: A Debian/Ubuntu-based system, e.g., Ubuntu, Debian, Linux Mint, or other systems in this family (The script is currently being tested only on the latest version of Ubuntu. Due to time constraints, I am unable to test it on other distributions.)
• Permissions: sudo (The script must be run without “sudo” in the terminal.)
• Required tools: curl, dpkg, grep, awk, jq, sha512sum, sha256sum, sudo, find, realpath, tar (The script automatically checks whether they are installed on the system and installs them itself if necessary.)

4. Run the script with the command: ./Multi_Package_Manager.sh (Before running it for the first time, you need to enter this command in the terminal: chmod +x ./Multi_Package_Manager.sh)
5. Add to the PATH variable (optional):

🤝 Collaboration and Support:

• The command_for_massive_test.txt file contains a list of commands for troubleshooting issues with the script. (If a file was not created, it means that an error occurred during that phase of testing; in this case, check the .txt file that was created last.)
• If you encounter a problem or want to suggest a new feature, please report it in this repository.
• If you’d like to support me financially, you can buy me a coffee: https://cuplink.to/fabiangamer2215 (the script is completely free; financial support is optional).
