Description
This error occurs when attempting to install a package that appears to be the same as an already installed version but is not bitwise identical. This commonly happens when a package has been rebuilt or re-signed, creating a technically different package despite having the same version number. Resolution requires either version number increment or complete removal of the existing package from all users.
Common Causes
📦 Package Identity Issues
Package identity conflicts often arise from rebuild or re-signing processes. Digital signatures might differ between versions. Package contents could have minor variations. Bitwise differences prevent direct replacement. Understanding package identity requirements is crucial for successful updates.
🔄 Version Management Problems
Version handling complications can prevent successful reinstallation. Version numbers might remain unchanged after updates. Multiple package versions could exist across users. Installation state might be inconsistent across the system. These version management factors require systematic resolution.
Resolution Steps
1️⃣ Version Assessment
Begin with comprehensive version status review. Check current package version across all users. Verify package digital signatures. Compare package contents and identities. Document all version-related findings.
2️⃣ Package Cleanup
If necessary, implement complete package removal process. Remove existing package from all user contexts. Clean up any residual package data. Verify complete removal across system. Document cleanup process and results.
3️⃣ Installation Strategy
Choose appropriate installation approach based on findings. Either increment package version number or ensure complete removal. Implement chosen strategy systematically. Test installation process thoroughly. Document successful installation steps.
Best Practices
👨💻 For IT Administrators
Effective package management requires attention to version and identity details. Implement comprehensive version tracking systems. Maintain documentation of package signatures and identities. Develop clear procedures for package updates. Create systematic approaches to version management. Consider implementing automated version control.
🔄 For Update Management
Successful update management requires attention to package identity and versioning. Develop clear processes for package updates. Maintain accurate documentation of version requirements. Implement thorough testing procedures for updates. Create comprehensive documentation of update procedures.
Troubleshooting Tips
When addressing reinstallation issues, focus on version and identity management. Consider version increments for updates. Ensure complete package removal when needed. Test installation processes thoroughly. Monitor package identity consistency.
Package reinstallation involves several critical factors. Version numbers must be managed carefully. Package removal must be complete. Digital signatures affect identity. Consider multi-user impact.
