I switched from windows 10 to Ubuntu 20.04.1 desktop single boot. Having SSD in my system the startup time in windows was in order of seconds. But in Ubuntu I am getting a start up time of 1 min 42 seconds.

This is what I got after running: systemd-analyze blame:

You can disable the NetworkManager-wait-online if you don't have a bunch of resources on the network that need to be connected before signing in. If you do not run your notebook on a corporate LAN, chances are you can go without it.

Do these things after Ubuntu eventually finishes booting:

  1. Open a terminal
  2. Disable the Network Manager wait:
    sudo systemctl disable NetworkManager-wait-online.service
  3. Reboot

Problem solved. If you do need to restore this function later, you can do so like this:

sudo systemctl enable NetworkManager-wait-online.service

Hope this helps
