SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Arch Linux's rolling-release model means updates can break packages, kernels, or services unexpectedly. This Skill provides a structured triage and remediation workflow so you can diagnose system issues methodically instead of guessing. ## Core Features & Use Cases - Systematic Triage: Step-by-step diagnosis using systemctl, journalctl, and pacman to isolate the root cause. - Copy-Paste Remediation: Ready-to-run commands for fixing broken packages, failed services, and update issues, each paired with verification commands. - Rollback & Cleanup: Guidance for downgrading packages, cleaning caches, and handling kernel update or reboot considerations. - Use Case: After a pacman -Syu update leaves a service failing to start, provide the problem summary and receive a numbered triage plan, fix commands, validation steps, and a rollback path. ## Quick Start Ask the assistant to triage your Arch Linux issue by describing the problem summary and any recent updates, optionally including a system snapshot and constraints.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix a broken Arch Linux system after an update?▼

Start by reviewing recent changes with journalctl and pacman logs, then follow a structured triage plan to isolate the failing component. Remediation typically involves reinstalling or downgrading affected packages, followed by verification commands to confirm the fix.

How to diagnose a failing systemd service on Arch Linux?▼

Use systemctl status to check the service state and journalctl -u to read its logs for error messages. The triage workflow walks through identifying the failure cause and provides copy-paste commands to resolve and validate it.

Can I roll back a pacman update on Arch Linux?▼

Yes, pacman keeps previously installed package versions in its cache, allowing downgrades to earlier releases. The Skill provides rollback and cleanup steps, including cache management, as part of every remediation plan.

What should I check after an Arch Linux kernel update?▼

Verify that the new kernel and initramfs were installed correctly, confirm bootloader entries are updated, and check that kernel modules still load. A reboot is usually required, and the workflow flags reboot considerations where relevant.

When is this Arch Linux triage approach not suitable?▼

It targets Arch-specific tooling like pacman and systemd, so it does not apply to other distributions such as Debian or Fedora. Hardware failures outside the OS layer also fall outside its diagnostic scope.
