  1. Go inside the /etc/apt/sources.list.d and look for moka-ubuntu-daily-xenial.list and delete it if more than one entry is present.
  2. Perform the following step for noobslab-ubuntu-apps-dependencies-xenial.list as well.
  3. Where the lines are starting with E, it means error. please check whether the URL is correct or not.
  4. For all the lines with W, those are warning. According to the logs we can conclude that the URL which you have put are not reachable.

First

For the configured multiple times error, in terminal, do this:

ls -al /etc/apt/sources.list.d/moka-ubuntu-daily-xenial.list*

You'll probably see this:

moka-ubuntu-daily-xenial.list
moka-ubuntu-daily-xenial.list:2
moka-ubuntu-daily-xenial.list:3
moka-ubuntu-daily-xenial.list:4

Leave moka-ubuntu-daily-xenial.list alone, and delete the remaining 3 with:

sudo rm /etc/apt/source.list.d/moka-ubuntu-daily-xenial.list:2
sudo rm /etc/apt/source.list.d/moka-ubuntu-daily-xenial.list:3
sudo rm /etc/apt/source.list.d/moka-ubuntu-daily-xenial.list:4

Second

For the 404 Not Found errors, see my previous answer to this same question at how to reset update sources

Third

Ignore the SHA1 errors.

Fourth

For the repository can't be authenticated errors, install y-ppa-manager and update the gpg authorization keys. In terminal, type:

sudo apt-get update
sudo apt-get install y-ppa-manager

Then start PPA Manager from the Unity dashboard.
