yum broken?

[abiko]

I'll be short with this one :)
After update manager told me that there are 186 updates for fedora 11 alpha, I've started to update the system.. Something broke :/
Now when using yum I get this error(s):

Loaded plugins: dellsysidplugin2, refresh-packagekit
rpmdb: Program version 4.7 doesn't match environment version 4.5
error: db4 error(-30971) from dbenv->open: DB_VERSION_MISMATCH: Database environment version mismatch

You upgraded the rpm packages. Between Alpha and Rawhide,
they made changes to rpm. Do the following:

cp -av /var/lib/rpm /var/lib/rpm.bak
rm -f /var/ilb/rpm/__db*
rpm -vv --rebuilddb

This will convert the old rpmdb to the newer format, using the newer db api.
Provided no errors were encountered, you can rm -rf /var/lib/rpm.bak
and proceed with your yum updates.

Also, yum seems to have an issue when updating the bash rpm.
I would advise not updating that along with others as you'll have a small mess
on your hands if yum breaks on you like it does me.

Thank you on your help.
Now running the KPackageKit to see where did it stop in the update process..
Again, thank you! :)

Thank you! This was very helpful.

By the way, #2 should be

2. rm -f /var/lib/rpm/__db*
