Dear Clemens and Marius,
problem solved! You were both right: It was a proxy issue as I know
now. Indeed these systems are configured to use an http/s proxy (but
the new admin hasn't been told so :-). Unfortunately Tomcat doesn't
seem to read the system wide configuration from the environment and
instead needs explicit Proxy configuration in bin/setenv.sh. After
that, the Distribution Wizard ran fine to the end and the Wiki is up and
running.
Thanks anyway for your help, hints and pointers. They were really
helpful and informative also for possible future issues :-)
Cheers
Frank

I thought one should set the -Djavax.net.debug in the CATALINA_OPTS , but I see
JAVA_OPTS is possible, too.
If these lots of "adding as trusted cert:" messages appear, then the option is
active indeed.
If you want to create more log messages from the xwiki-webapp, you can edit the file
webapps/xwiki/WEB-INF/classes/logback.xml
Setting the root logger level there to "debug" will create tons of output ...
Maybe it is sufficient to enable some network related loggers, like:
<logger name="org.apache.http" level="trace" />
<logger name="org.eclipse.aether" level="trace" />
which will create tons of output either, but hopefully with somewhat higher relevance
density.

hope this helps

I have to admit that if it is not the
proxy-settings then I am getting somewhat desperate about how to diagnose the problem.
I guess one could try to get stack traces from the server while it is starting up
and use the java option "-Djavax.net.debug=all" (dumps lots of stuff to the
standard output) to see if it tries to open connections to extensions.xwiki.org
but I guess all one can get from that is that the server opens connections and then it
waits till timeout ...
I've done this through setting the environment variable $JAVA_OPTS to
"-Djavax.net.debug=all" prior to running $tomcat_home/bin/catalina.sh.
Is that the right place? I also set the following loggin levels in
$tomcat_home/conf/logging.properties:
java.util.logging.ConsoleHandler.level = FINEST
1catalina.org.apache.juli.AsyncFileHandler.level = FINEST
