由於/var/lib/rpm/內的db檔Packages壞掉,
如照一般的rebuilddb仍會出錯；須先重置Packages檔方能rebuilddb
主機內的rpmdb是 BerKeley DB 5.2.x 故底下一些開頭有db52_...(from:db52-utils...)須依自己使用的版本更改
執行次序如下：
# cd /var/lib/rpm
# mv Packages Packages-ORIG
# db52_dump Packages-ORIG | db52_load Packages
# /usr/lib/rpm/bin/rpmdbchk --dbpath=/var/lib/rpm
# db52_recover -ev -h /var/lib/rpm # <ref.2>
# rpm --rebuilddb -vvv # <ref.2>
