RPM How-To for end users

Basic informations for end users about installing, upgrading and removing packages with RPM and YUM.

Note about upgrading from 2010 RPM builds

Newer RPM builds are now using Berkeley DB for storing package informations, while previous builds were using SqLite? 3 for this task. Since SqLite? support is being phased out, RPM moved to BDB. After updating you need to convert the old database to the new format: you can check this running

rpm -qa

at the command prompt; you will get a SIGSEV error or a message about wrong database format:

[E:\]rpm -qa
rpmdb: __db_meta_setup: /@unixroot/var/lib/rpm/Packages: unexpected file type or
 format
error: cannot open Packages index using db3 - Invalid argument (22)
error: cannot open Packages database in /@unixroot/var/lib/rpm
rpmdb: __db_meta_setup: /@unixroot/var/lib/rpm/Packages: unexpected file type or
 format
error: cannot open Packages database in /@unixroot/var/lib/rpm

To upgrade the database, use the following command sequence:

rpm --define '_dbapi 4' --rebuilddb
mv /@unixroot/var/lib/rpm /@unixroot/var/lib/rpm.bak
mv /@unixroot/var/lib/rpm.rebuild /@unixroot/var/lib/rpm

You can test operation running

rpm -qa

you will get the list of installed packages. The older SqLite? databases are now saved into mv /@unixroot/var/lib/rpm.bak, if everything is ok you can delete this directory.
