oma - Oh My Ailurus / Package Manager for AOSC OS

Features | Install | Contribute

oma is an attempt at reworking APT's interface, making it more user-friendly, more robust against common user errors, and more performant during package downloads. oma also integrates closely with AOSC OS's various system management functions, from mirror configuration, topic (testing) repository enrollment, to system feature protection.

For a more detailed overview on oma's features, see features.

oma is also available for other dpkg-based OS.

Please see Install.

Features

• Clear-and-Simple Interface: Colorful and TUI-heavy interface, with clear marking for key information and simplified commands for common operations.
• Faster Downloads: Faster package downloads, powered by the performant reqwest HTTP and multi-threaded downloads.
• Smart Search: Leveraging the indicium search engine for more relevant package search results.
• Fool-Proofing Mechanisms: Protection against system failures through a combination of mechanisms - active prevention against removal of essential packages, clear marking for potentially dangerous operations, and a disaster recovery mechanism through undo command.
• System Feature Protection: Informing and advising against uninstalling critical system components by detecting System Feature Markers in key component packages (AOSC OS only).
• System Status Integration: Integration with system daemons, allowing oma to warn against performing package management operations on battery power, as well as actively inhibiting accidental reboots and suspends.
• Compatibility with Other dpkg-based OS: Bringing a more friendly package management experience to major dpkg-based distributions like Debian, Ubuntu, deepin, and openKylin.
• Distro-specific Integration: Supporting not only AOSC OS-specific features such as topic repository enrollment and mirror management, but also distro-specific services such as Ubuntu Pro.
