Error during update 

A problem occurred during the update. This is usually some sort of 
network problem, please check your network connection and retry.

  1. I don't think it is a network problem but perhaps a procedural one.

    To upgrade from the command line you need to follow these steps:

    Open up a terminal window Ctrl Alt t

    Issue the command sudo apt-get upgrade

    Enter your user password

    Look over the list of available updates and decide if you want to go through with the entire upgrade

    To accept all updates click the y key and hit Enter.

    Other than that there is a new procedure too... acknowledgements to itsfoss

  2. Possibly you need to update your 16.04 to the latest state first before doing the upgrade to 18.04, try.

    sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
