Installation problem on Ubuntu 18.04

Hello,

I am trying to install Nextflow on Ubuntu 18.04.6 LTS.

I got following Error:

USAGE: java <options> -jar ../../.nextflow/framework/21.10.6/nextflow-21.10.6-one.jar

  capsule.version - Prints the capsule and application versions.

  capsule.resolve - Downloads all un-cached dependencies.

Unable to initialize nextflow environment

Java version:
openjdk version "11.0.14.1" 2022-02-08
OpenJDK Runtime Environment (build 11.0.14.1+1-Ubuntu-0ubuntu1.18.04)
OpenJDK 64-Bit Server VM (build 11.0.14.1+1-Ubuntu-0ubuntu1.18.04, mixed mode, sharing)

I am asking for suggestion how to solve this Error.

Regards,

Have you tried installing on a different wifi? Work/institutions might be blocking some of the sources.
I went through the ringering trying to figure out what was wrong, then i installed via conda on a different network and all was well.
