OS: Ubuntu 22.03

Unfortunately the installation doesn’t work and I don’t know what the problem is, can you help me? I am a beginner, so please write your questions or solutions as simply as possible

I have taken the following steps:

sudo apt install openjdk-17-jre-headless

openjdk version "17.0.10" 2024-01-16
OpenJDK Runtime Environment (build 17.0.10+7-Ubuntu-122.04.1)
OpenJDK 64-Bit Server VM (build 17.0.10+7-Ubuntu-122.04.1, mixed mode, sharing)

sudo wget https://maven.xwiki.org/xwiki-keyring.gpg -O /usr/share/keyrings/xwiki-keyring.gpg

sudo wget "https://maven.xwiki.org/stable/xwiki-stable.list" -O /etc/apt/sources.list.d/xwiki-stable.list

sudo apt-get update

apt-cache search xwiki

sudo apt install xwiki-tomcat9-pgsql

I have not received an error message, but I cannot open the URL : localhost:8080 or localhost:8080/xwiki

I get the following output when I write the locate xwiki command. Are there any things missing?
locate_command.txt (252.4 KB)
