Install Java runtime and Nextflow

Nextflow is quite easy to install:

  • install a java run time for Nextflow if not available
sudo apt-get update
sudo apt install -y default-jre

# download
curl -s https://get.nextflow.io | bash
# move to any $PATH location or add it to $PATH
# e.g.
sudo mv nextflow /usr/bin/

Update Nextflow to a newer version

  • just execute this:
  • alternatively use the "build in" nextflow upgrade
# downloads the newer version
curl -s https://get.nextflow.io | bash
# replace the old version with the newer version
sudo mv nextflow /usr/bin/

Specific Nextflow versions

  • if you need a specific older nextflow version for some reason, go to the release page
  • under assets you find a file called "nextflow-RELEASENUMBER-all" (replace RELEASENUMBER with the actual number they provide on the release page)
  • download this file and move it to e.g. /usr/bin/ or call it directly ./nextflow-RELEASENUMBER-all run ...
  • instead of nextflow run ... you do nextflow-RELEASENUMBER-all run ...
