What could be the reason?

Thanks in advance.

I suspect you were not lucky, and the server was not in a great shape when you tried to install.

3

I was suspecting that it might be due to some proxy configuration but a test page with the following groovy worked fine:
{{velocity}}
$xwiki.getURLContent(“https://nexus.xwiki.org/nexus/content/groups/public/org/xwiki/platform/xwiki-platform-distribution-flavor-mainwiki/17.10.0/xwiki-platform-distribution-flavor-mainwiki-17.10.0.pom”)
{{/velocity}}

@tmortagne thanks for the reply. What did you exactly suspected regarding the “shape” of the server?

4

Just that you tried when the server was in a bad state and that it might work now for example.

5

Well, that’s not the case. It’s a persistent error. Tried zillions times but no luck. Won’t be able to evaluate the xwiki experience without extensions and customisations it offers.

6

If you tried many times and always have the exact same error, then it must be something on your side, as the flavor install works well for me.

That does not looks like the root cause of the error, so it’s not easy to deduce anything from it.
