• GeoLiteCity Database file fails to download or install, when you run ant fresh_install: There are two common errors that may occur:

  • If your error looks like this:

    Code Block
    [get] Error getting http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz to /usr/local/dspace/config/GeoLiteCity.dat.gz BUILD FAILED /dspace-release/dspace/target/dspace-installer/build.xml:931: java.net.ConnectException: Connection timed out

    it means that you likely either (a) don't have an internet connection to download the necessary GeoLite Database file (used for DSpace Statistics), or (b) the GeoLite Database file's URL is no longer valid. You should be able to resolve this issue by following the "Manually Installing/Updating GeoLite Database File" instructions above.

  • Another common message looks like this:

    Code Block
    [echo] WARNING : FAILED TO DOWNLOAD GEOLITE DATABASE FILE [echo] (Used for DSpace Solr Usage Statistics)

    Again, this means the GeoLite Database file cannot be downloaded or is unavailable for some reason. You should be able to resolve this issue by following the "Manually Installing/Updating GeoLite Database File" instructions above.
