I want to install last version of ocaml on Ubuntu 16.04 but when I had the PPAs from ocaml website, it displays that there are no release files.
I can't install ocaml of official repositories for they are not up to date.
I follow Ocaml website's tutorial for ubuntu up to date install :
sudo add-apt-repository --yes ppa:avsm/ppa
sudo apt-get update -qq
W: The repository 'http://ppa.launchpad.net/avsm/ppa/ubuntu xenial Release' does not have a Release file. E: Failed to fetch http://ppa.launchpad.net/avsm/ppa/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
