How to perform a more recent installation of Iperf than the one included in Ubuntu / Debian / Mint ?

  1. Removing the old version: sudo apt remove iperf3 libiperf0
  2. Install the dependency: sudo apt install libsctp1
  3. Take a recent Ubuntu distribution from https://launchpad.net/ubuntu/+source/iperf3
  4. Download iperf3_3.xx-1_amd64.deb and libiperf0_3.xx-1_amd64.deb packages (use amd64 version for a standard version of Ubuntu)
  5. Install downloaded packages: sudo dpkg -i libiperf0_3.xx-1_amd64.deb iperf3_3.xx-1_amd64.deb
  6. Remove downloaded packages that are now unnecessary: rm libiperf0_3.xx-1_amd64.deb iperf3_3.xx-1_amd64.deb
