Hi guys,
I just tried to install XWiki using the Debian packages as described in the official docs.
These are all the steps I took:
sudo apt install gnupg2
wget -q “https://maven.xwiki.org/public.gpg” -O- | sudo apt-key add -
sudo wget “https://maven.xwiki.org/stable/xwiki-stable.list” -P /etc/apt/sources.list.d/
sudo apt-get update
apt-cache search xwiki
sudo apt-get install xwiki-tomcat9-mariadb
sudo nano /etc/xwiki/xwiki.cfg //Setting validationKey, encryptionKey and superadminpassword
Now if I visit the url
8080/xwiki
I get to
8080/xwiki/bin/view/Main/
with a completely white website where I only get a 503.
In the logs I found these errors:
05-Nov-2020 15:16:55.445 SEVERE [http-nio-8080-exec-7 - http://example.de:8080/xwiki/bin/view/Main/] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [action] in context with path [/xwiki] threw exception

Unfortunately I have no clue why this is not working. And I couldn’t find anything in the installation instructions that I forgot.
Do you have an idea?
Thanks!
