yum Error:rpmdb open failed
This is how I fixed my problem.
You may fix this by cleaning out rpm database. But first, in order to minimize the risk, make sure you create a backup of files in /var/lib/rpm/
using cp
command:
mkdir /root/backups.rpm.mm_dd_yyyy/
cp -avr /var/lib/rpm/ /root/backups.rpm.mm_dd_yyyy/
The try this to fix this problem:
# rm -f /var/lib/rpm/__db*
# db_verify /var/lib/rpm/Packages
# rpm --rebuilddb
# yum clean all
And finally verify that error has gone with the following yum command
# yum update
