+There are four things involved in an RPM upgrade: +
++Gaining information about the RPMs on your system: +"make rpmstatuspost" +(see Viewing the status of your machine) +will tell you about RPMs which do not belong (are "external" +to LON-CAPA). It will also tell you if you have "out-of-date" +RPMs which should maybe be upgraded. Important specification +files for RPM installation are CVS:doc/otherfiles/rpm_list.txt +and CVS:doc/otherfiles/cd_rpms.txt. +
++Upgrade existing RPMS from a trusted source: +RPMs are currently available at +
+http://install.lon-capa.org/3.1/currentcdsource/RedHat/RPMS ++For example, to upgrade your LON-CAPA-systemperl RPM, you +would enter commands like +
+wget http://install.lon-capa.org/3.1/currentcdsource/RedHat/RPMS/LON-CAPA-systemperl-3.1-1.i386.rpm+ +
+(then as root) rpm -Uvh --force LON-CAPA-systemperl-3.1-1.i386.rpm +
+Remove RPMs which do not belong: +If an RPM should NOT be on your system (like apmd), then you want +to remove this RPM. Since RedHat is a little erroneous when +it comes to dependencies, you may wish to use the --nodeps flag. +
+rpm -e --nodeps apmd-3.0final-2.i386.rpm ++ +
+Add new RPMs: +Use the same command as for upgrading. +
+(as root) rpm -Uvh --force icewm-1.0.5-gnome.i386.rpm ++We often use icewm as our development machine window manager given the +RedHat 6.2 bugs involving enlightenment and gnome. +
