yum fails on my VPS / the RPM database on my VPS is corrupt

14 January, 2015 (19:01) | VPS | By: sblogadmin

Under certain conditions the RPM database used by yum will become corrupt. Here is how to resolve this issue. You may see an error such as “Warning: RPMDB altered outside of yum” or “error: rpmdbNextIterator”

1. Take a backup FIRST, before trying to have rpm repair the database.

cd /var/lib
tar zcvf /var/preserve/rpmdb-[today's date].tar.gz rpm

Verify integrity with

cd /var/lib/rpm
rm -f __db*      # to avoid stale locks
/usr/lib/rpm/rpmdb_verify Packages

Next run the following:

mv Packages Packages.orig
/usr/lib/rpm/rpmdb_dump Packages.orig | /usr/lib/rpm/rpmdb_load Packages
/usr/lib/rpm/rpmdb_verify Packages
rpm -qa

Finally rebuild the database:

rpm -vv --rebuilddb

for the error :

error: rpmdbNextIterator


mv /var/lib/rpm/Pubkeys /var/lib/rpm/Pubkeys.backup
rpm --rebuilddb -vv to recreate the index.
