installation update via install.sh fails

[Peter Baumann]

trying to update an existing installation I get:

$ ./install.sh 
Welcome to the rasdaman installation process. To find more information about rasdaman,
please visit http://rasdaman.org/.

This script aims to install all the rasdaman dependencies and then install and
configure rasdaman to work out of the box. In doing this, it will modify your
system by installing extra packages or reconfiguring existing ones. To find out
more about this installer, run again with option -h. Proceed with care.

Please choose one of the installations profiles displayed below or just press
enter to install the default one:

    [0] default     This profile will install rasdaman in /opt/rasdaman and will
                    also deploy petascope and secore in your tomcat folder. It uses
                    the recommended storage backend of rasdaman, SQLite/Filestorage.
    [1] postgres    This profile will install rasdaman in /opt/rasdaman using a
                    postgresql as a storage backend (deprecated). It will also
                    deploy petascope and secore in your tomcat folder.
    [2] petabeded   This profile will install rasdaman in /opt/rasdaman and it will
                    deploy petascope and secore using an embedded jetty container.
    [9] none        If you wish to customize your profile (for example, choosing
                    your installation path, storage backend and many other options),
                    please visit http://rasdaman.org/wiki/Installer and follow
                    the instructions there.
Please choose one of the numeric options above (default: 0)? 
JSON profile configurations are not supported anymore by this version of the installer.
Please specify a profile configuration in the TOML format, e.g. ./install.sh -j profile.toml
A default, fully documented example can be found at http://rasdaman.org/wiki/InstallerConfig

If you were executing update_rasdaman.sh, then please execute one of the following commands instead:
  ./install.sh                 - if you used the default profile
  ./install.sh -j profile.toml - if you used a custom profile
