[SOLVED] yum and rpm get a db5 error

[JuhaniJaakola]

I upgraded from Fedora 16 to Fedora 17 using the DVD. After the upgrade I issued yum update for local files for rpm and yum packages which I had downloaded via yumdownloader. It updated yum and rpm to the latest packages. I wondered why it did not load the new repos from the servers?

After that yum and rpm do not work any more:

# yum update
error: db5 error(22) from dbenv->open: Invalid argument
error: cannot open Packages index using db5 - Invalid argument (22)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Error: rpmdb open failed
# rpm --rebuilddb
error: db5 error(22) from dbenv->open: Invalid argument
error: cannot open Packages index using db5 - Invalid argument (22)

Any ideas?

The usual way fixed this:

# cd /var/lib/rpm/
# mv __db.00* /tmp
# rpm --rebuilddb
