There are three steps for upgrading the software on your LON-CAPA server.

Upgrading LON-CAPA files

Download the most current loncapa-current.tar.gz.

wget http://install.lon-capa.org/versions/loncapa-current.tar.gz
tar xzvf loncapa-current.tar.gz
cd loncapa

The UPDATE command will refresh your filesystem with all the latest LON-CAPA software.

./UPDATE

Checking your Linux RPMs

If you are using RedHat, the CHECKRPMS command will check the RPMs on your machine against an FTP repository. Otherwise, you may need to update software manually.

./CHECKRPMS
