DepParse

A comprehensive parser for yum/dnf package dependency error logs in RHEL 8/9 format that analyzes dependency chains and provides actionable fix recommendations.

Features

• ✅ Parses complete dependency chains including "requires" relationships
• ✅ Identifies root cause missing dependencies
• ✅ Provides exact installation commands to resolve issues
• ✅ Organizes output by problem number for easy navigation
• ✅ Queries repositories to find available package versions
• ✅ Single comprehensive log file - all analysis in one place
• ✅ Clean stdout summary with quick fix commands

Quick Start

1. Add your complete dependency error into yumlog.txt in the same directory as yumlooper.sh (Example included)
2. Run the script:

   ./yumlooper.sh

3. See the fix command in the output and run it, or review the full analysis in the log file

Usage

./yumlooper.sh              # Standard analysis
./yumlooper.sh -v           # Verbose mode (for future debugging features)
./yumlooper.sh --help       # Show help

Output

Standard Output (stdout)

Shows a clean summary with the most important information:

Full analysis saved to: depparse_analysis.log

Analysis Log File: depparse_analysis.log

A single comprehensive file containing:

1. DETAILED DEPENDENCY CHAINS - Tree-structured view of all problems

   === Problem 1 ===
   Installed: python3-pip-9.0.3-20.el8.noarch
     \-- MISSING: platform-python-pip = 9.0.3-22.el8
         (needed by: python3-pip-9.0.3-22.el8.noarch)
   

2. FAILED PACKAGES SUMMARY - Which packages failed and why

3. ROOT CAUSE - MISSING DEPENDENCIES - List of missing dependencies

4. REPOSITORY ANALYSIS - Available packages from enabled repos

5. RECOMMENDED FIXES - Exact commands to fix the issues

   To fix the dependency issues, install/update these packages:
   
     • jansson-2.14-1.el8 (from rhel-8-for-x86_64-baseos-rpms)
     • json-c-0.13.1-3.el8 (from rhel-8-for-x86_64-baseos-rpms)
     • platform-python-pip-9.0.3-24.el8 (from rhel-8-for-x86_64-baseos-rpms)
   
   Installation commands:
   ---------------------
   yum install jansson json-c platform-python-pip
   
   # Or to update:
   yum update jansson json-c platform-python-pip
   

To view the full analysis:

cat depparse_analysis.log
# or
less depparse_analysis.log

What It Parses

• problem with installed package - Identifies problematic packages
• nothing provides <dependency> - Root cause missing dependencies
• package X requires Y - Dependency chain relationships
• Repository queries via yum whatprovides - Available package versions

Why One Log File?

• Simpler - Everything in one place, no juggling multiple files
• Complete - Full context and analysis together
• Portable - Easy to share the entire analysis
• Clean stdout - Shows only what you need to act on immediately
