RPM database Borked after recent update to rpm-4.6.1-1

[LinuxTom]

After today's round of updates installed rpm-4.6.1-1 the system choked on reboot while loading akmods and spit out the following messages

rpmdb: /var/lib/rpm/Packages: unsupported hash version: 9
error: cannot open Packages index using db3 - Invalid argument (22)

The traditional approach of just removing the __db.0* (database files), and running rpm --rebuilddb did not work. db_recover produced the output:

Program version 4.7 doesn't match environment version 4.5

A bit of trial and error resolved this via...

cd /var/lib/rpm
rm -fv __db*
mv -v Packages Packages-BAK
db_dump Packages-BAK | db45_load Packages
rpm -vv --rebuilddb

I see no mention of anyone else having this problem, but if you run across it, these steps should rectify the situation.

I have Fedora 10 and my rpm data base also got corrupted i tried the steps you suggested. But the third step is giving error that
db_dump: command not found

Do you have any other suggestion to solve this problem, I am a bit new in all these things.

thanks

Sorry about the delay in response, I lost track of this thread.

It should be in /usr/bin/db_dump assuming the db4-utils package was installed properly.

You would also need compat-db45 package which provides /usr/bin/db45_load. But unfortunately if rpm is broken, you can neither verify the installation of those packages, nor install them if they aren't currently installed.
