Archive note, 8 October 2026. This is a 2013 duplicate-package troubleshooting account; the exact CentOS release was not retained in the post. rpm -e --nodeps --justdb alters the package database while bypassing dependency checks, without removing the corresponding files. Preserve a recoverable system/database backup and review an explicit package list before any such intervention. The historical command is not a current general-purpose repair recipe.

for p in $(yum update | grep "is a duplicate"  | awk ' { print $6 }'); do rpm -e 

--nodeps --justdb  $p ; done
