1.2 ! harris41 15: <LI>As root, run the script <A HREF="http://install.lon-capa.org/verify/scripts/loncapaverifypackages">
1.1 harris41 16: loncapaverifypackages</A>. This script should be present on your system in the file
17: /usr/sbin/loncapaverifypackages. If packages are out-of-date, this script will output
18: the out-of-date packages. Packages that this script identifies as "should not be here",
19: are packages that you may wish to remove to improve system security. (These packages
20: may represent important modifications of your institution, so do with care. Removing
21: packages is done with the command: <TT>rpm -e --nodeps PACKAGE_NAME</TT>.

35: <LI>As you run /usr/sbin/loncapaupgradepackages or enter in <TT>rpm -Uvh --force</TT> commands, you may
36: see messages appear on your screen such as:
37: <BR><TT>warning: /etc/httpd/conf/access.conf saved as /etc/httpd/conf/access.conf.rpmsave</TT>
38: <BR>You can probably just type in commands like:
39: <BR><TT>cp /etc/httpd/conf/access.conf.rpmsave /etc/httpd/conf/access.conf</TT>
40: <BR>to restore your configurations. However, it is worthwhile to use the 'diff' command
41: to make sure that you are not accidentally losing important updates to the configuration
42: files.
43: <LI>Alternatively, you can run /usr/sbin/<A HREF="http://www.lon-capa.org/install/verify/scripts/loncaparestoreconfigurations">loncaparestoreconfigurations</A> to "smartly" run through the system and restore LON-CAPA configuration values.

45: <LI>Should you wish to automate all of this, you can (at your own risk) enable a script which will
46: do all of this automatically. <B>This definitely should NOT be implemented on a system that students
47: are using)</B>. You can enable this script by entering the command:
48: <TT>cp /usr/sbin/<A HREF="http://www.lon-capa.org/install/verify/scripts/loncapaautoupgrade">loncapaautoupgrade</A> /etc/cron.daily/loncapaautoupgrade</TT>

52: <P>
53: In the future, LON-CAPA will be a versioned system that is released via CD.
54: The upgrade procedure will be to insert the CD and follow instructions. The CD
55: upgrade procedure is already defined and somewhat implemented, but awaits
56: completion.
