Failed to install a flavor

Help / Discuss

Hi! I’ve managed to install a brand new XWiki 13.8 instance in this environment:

Apache Tomcat/9.0.45
MySQL Server version: 8.0.26 Source distribution
mysql-connector-java-8.0.26.jar

CentOS Linux release 8.4.2105

[rjr@e220i059h057w ~]$ java -version
openjdk version "1.8.0_302"
OpenJDK Runtime Environment (build 1.8.0_302-b08)
OpenJDK 64-Bit Server VM (build 25.302-b08, mixed mode)
[rjr@e220i059h057w ~]$

Somehow, the installation of a flavor (step 2) failed, and I ended up with an empty wiki. I found this line in catalina.out:

2021-10-09 21:25:59,753 [extension.index job group daemon thread - org.xwiki.extension.index.internal.job.ExtensionIndexJob@3d455216([extension, index])] WARN o.x.e.i.i.j.ExtensionIndexJob - Failed to get remote extension from repository [extensions.xwiki.org:xwiki:https://extensions.xwiki.org/xwiki/rest]: IOException: Invalid answer [504] from the server when requesting [https://extensions.xwiki.org/xwiki/rest/repository/search?start=300&number=100&q=]

I think I remember there is a way to force the whole process again without having to delete the database, but I don’t remember how! Please, could you help me?

I would like to reproduce and document the error if it appears again!

Thanks!

Hi Ricardo, yes it’s in the doc of the Distribution Wizard, see https://www.xwiki.org/xwiki/bin/view/Documentation/UserGuide/Features/DistributionWizard#HTroubleshooting

In this case only, you can remove the …/jobs/status/distribution/status.xml file located inside your permanent directory (/var/lib/xwiki/… for APT installation or /var/lib/tomcatX/webapps/… for WAR installation).

Thanks

Hi, Vincent! Thanks for the answer. I’m concentrating on the paragraph you quoted above:

In this case only, you can remove the …/jobs/status/distribution/status.xml file located inside your permanent directory (/var/lib/xwiki/… for APT installation or /var/lib/tomcatX/webapps/… for WAR installation).

First, I confirmed that I’ve correctly set up a permanent directory:

2021-10-11 13:21:33,735 [main] INFO o.x.e.i.ServletEnvironment - Using permanent directory [/var/lib/xwiki/data]

I’m not able to find a single status.xml file neither in this folder (I downloaded and exploded the war file, then removed it), nor in the whole system:

[root@e220i059h057w /]# find ./ -name “status.xml”
[root@e220i059h057w /]# locate status.xml
/usr/share/mime/message/delivery-status.xml

The wizard appeared at installation time, but failed both with the standard and the demo flavors. Please, must I forget about this, delete the database and recreate it or do you consider that the situation deserves some more attention?

Thanks!

The file is in [perm dir root]/jobs/status/distribution. In recent versions, it’s zipped apparently (status.xml.zip)

@tmortagne seems you forgot to update the doc. I can do it but I don’t know when this change was introduced.

answer: in 13.7RC1: Loading...

Found! Thanks! Demo Favor Installation on its way!

For the record: after renaming status.xml.zip, restarting Tomcat and accessing the wiki, I read this before the Distribution Wizard appears:

Does it make any sense for you? Thanks!

That’s not a problem. It means you probably closed your browser tab before the content was fully sent to it by the server side.
