E: Some index files failed to download. They have been ignored, or old ones used instead.
what can i do?
You can do one of two things.
This ppa has not been updated since 2013 so it may be wise to not use it for now. You can however download the most recent version of nitrotasks from https://launchpad.net/~cooperjona/+archive/ubuntu/nitrotasks/+packages and install it manually.
First, to delete the outdated ppa open a terminal and execute the following commands:
sudo rm /etc/apt/sources.list.d/cooperjona-ubuntu-nitrotasks-utopic.list*
Now, update your package list:
sudo apt-get update
Finally, download the desired software directly from the ppa and install it:
wget https://launchpad.net/~cooperjona/+archive/ubuntu/nitrotasks/+files/nitrotasks_1.5-0%7E31%7Esaucy1_all.deb
install it:
sudo dpkg -i nitrotasks_1.5-0~31~saucy1_all.deb
resolve dependencies:
sudo apt-get -f install
