[xwiki-users] XWiki 7.4 Distribution Wizard says: "We couldn't find any extension with id 'org.xwiki.enterprise:xwiki-enterprise-ui-mainwiki' and version '7.4'."

Hi,
when working through the Distrbution Wizard of our freshly installed
XWiki Enterprise 7.4 (WEB installation), at step 1 (User Interface) we
are faced with the following message:
"
We couldn't find any extension with id
'org.xwiki.enterprise:xwiki-enterprise-ui-mainwiki' and version '7.4'.
Make sure you have the right extension repositories configured.
"
The complete creenshot can be found at http://imgur.com/Uc2F9pr.
I've copied the file
"org.xwiki.enterprise:xwiki-enterprise-ui-mainwiki-7.4.xar" (from
http://extensions.xwiki.org/xwiki/rest/repository/extensions/org.xwiki.ente…)
into WEB-INF/extensions to no avail.
The installation instructions doesn't mention any required step
regarding the configuration of extensions or extension respositories or
where these respositories are. Therefore I'm a little bit at a loss here.
Our system is running on OpenSuSE 13.1 with PostgreSQL 9.2.14 (from
repo), Apache Tomcat 8.0.30 (manually installed) and XWiki Enterprise
7.4 (WEB, manually installed).
Any pointer to fix this problem are appreciated.
Cheers
Frank

Hi Frank,
You need to make sure you have internet access. If you are behind a proxy
you should check
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HRunningXW…
. It may also happen that the extensions.xwiki.org is down at the moment
you try to run the Distribution Wizard. You should try again a bit later.
Hope this helps,
Marius

Hi Marius,

http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HRunningXW…
We have internet access and we are not using a proxy (afaik). However
although we /can/ reach the internet, our hosts are not reachable /from/
the internet (NAT) but I don't assume that's required.
Also I cannot find any "connection refused" exceptions in tomcat/logs/*.
. It may also happen that the extensions.xwiki.org is
down at the moment
you try to run the Distribution Wizard. You should try again a bit later.
I'm trying since over 24 hours now, at least 10-15 times. I cannot
imagine, that extensions.xwiki.org was down all the time. It is
reachable by https right now and I still experience the error message
Is there a way to manually install this extension?
Frank
Hope this helps,
Marius

some random ideas:
- in WEB-INF/xwiki.properties: are any settings for extension.repositories=... enabled
or are they all commented?
They should be all commented, of if there are active ones (even empty ones),
at least the two "defaults" must be defined, too:
extension.repositories=maven-xwiki:maven:http://nexus.xwiki.org/nexus/conte…
extension.repositories=extensions.xwiki.org:xwiki:http://extensions.xwiki.o…
If I uncomment just a lone 'extension.repositories=' I get exactly the error in
the screenshot
- Another idea: any chance there is a name resolution problem on the server?
extensions.xwiki.org should resolve to 5.135.240.206 (currently)
"curl http://extensions.xwiki.org" -> should return a 302 to the Start
page

I have to admit that I have been running out of ideas why the wiki cannot get a connection
while "curl" can.
One last try: has the gateway connecting the local network to the internet an application
firewall or the like ?
Something that sniffs user-agents for http connections and only allows "known
ones" ?
The java client used by the XWiki installation wizard might be emulated with:
curl --user-agent "history" http://extensions.xwiki.org
if this works, too, I have to admit I have no clue why it does not work.
(Btw, there should be an error message in the log files. Is there anything like that?)

why the wiki cannot get a connection while "curl" can.

Not to my knowledge, but see below

$
if this works, too, I have to admit I have no clue why
it does not work.
(Btw, there should be an error message in the log files. Is there anything like that?)
In fact, there is a single error being printed to logs/catalina.out
/after/ I click the "continue" button in the first step of the
Distribution Manager:
[...]
2016-01-28 13:36:53,762 [Active Installs Ping Thread] WARN

to [http://extensions.xwiki.org/activeinstalls]. Error =
[ConnectException: Connection timed out]. Will retry in [86400] seconds...
[...]
I don't know what an "Active Installation ping" is, but in fact while I
seem to be able to access this webpage:
$ curl http://extensions.xwiki.org/activeinstalls
{
"status" : 200,
"name" : "Bobster",
"version" : {

"build_snapshot" : false,
"lucene_version" : "4.7"
},
"tagline" : "You Know, for Search"
}
$
I cannot `ping` it:
$ ping extensions.xwiki.org
PING www.xwiki.org (104.31.71.57) 56(84) bytes of data.
^C

76 packets transmitted, 0 received, 100% packet loss, time 75445ms
$
Does the Distribution Manager execute a real "ping" command even though
the webpages are accessible? And if yes, how can I avoid this? I doubt
that our networking dept. will adapt any gateway configuration to to
make a single software installation possible :-}

Hi Frank,
Hi Clemens,
bad info given by me here, sorry; it should read:
curl --user-agent "XWikiExtensionManager" http://extensions.xwiki.org
anyway, this seems not to be the problem ... because the other bogus user agent works as
well:

ideas why the wiki cannot get a connection while "curl" can.

firewall or the like ?

No, there is no ping or such; well, it relies on the library: "HTTP Components":
https://hc.apache.org/ to do the job.
I have to admit that I do not know exactly if this library does or does not send a ping
first, but I do not think it does.
Even if it were so, it is not the case of the problem, as I cannot ping
extensions.xwiki.org either, and install works from here.
The "timeout" error message seems to indicate that the connection never gets an
error but is simply dropped somewhere.
I do not think extensions.xwiki.org drops the connection - as you can get there via curl
...
Any chance the application server uses some proxy settings, as described at the following
link, but they happen to be incorrect?
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HRunningXW…
That might explain the timeout despite the server being able to reach the installation
repositories normally (i.e. via curl).
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 ...
If you just want to get the server running with a proper UI anyway, I have written up a
little HowTo :
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/FillLocalMavenRepository
To use it, one needs to install + configure maven, however ...
I am still using maven 3.0.4 from
http://archive.apache.org/dist/maven/maven-3/3.0.4/binaries/apache-maven-3.…
but to just donwload the UI-packages any version of 3.x should "just work".

I don't know what an "Active Installation ping" is, but in fact while I
seem to be able to access this webpage:

I cannot `ping` it:

Does the Distribution Manager execute a real "ping" command even though the
webpages are accessible? And if yes, how can I avoid this? I doubt that our networking
dept. will adapt any gateway configuration to to make a single software installation
possible :-}

No, there is no ping or such; well, it relies on the library: "HTTP
Components": https://hc.apache.org/ to do the job.
I have to admit that I do not know exactly if this library does or does not send a ping
first, but I do not think it does.
Even if it were so, it is not the case of the problem, as I cannot ping
extensions.xwiki.org either, and install works from here.
The "timeout" error message seems to indicate that the connection never gets an
error but is simply dropped somewhere.
I do not think extensions.xwiki.org drops the connection - as you can get there via curl
...
Any chance the application server uses some proxy settings, as described at the following
link, but they happen to be incorrect?
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HRunningXW…
That might explain the timeout despite the server being able to reach the installation
repositories normally (i.e. via curl). 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
and -Djavax.net.debug=all to $tomcat_home/bin/setenv.sh
#!/bin/sh
export JAVA_OPTS="${JAVA_OPTS} -Djava.awt.headless=true
-Djavax.net.debug=all"
Other than providing "hundreds" of "adding as trusted cert:"
notifications in logs/catalina.out it doesn't provide any additional
information. Or that's not the right place to raise the verbosity level
of the Apache HttpComponents library.
If you just want to get the server running with a
proper UI anyway, I have written up a little HowTo :
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/FillLocalMavenRepository
To use it, one needs to install + configure maven, however ...
I am still using maven 3.0.4 from
http://archive.apache.org/dist/maven/maven-3/3.0.4/binaries/apache-maven-3.…
but to just donwload the UI-packages any version of 3.x should "just work".
I'll have a look at this.

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.

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
