To change the apt repository list you need to edit /etc/apt/sources.list.

If this answer does not solve your problem, please edit your question and paste the content of /etc/apt/sources.list.

Use sudo nano /etc/apt/sources.list in the terminal and then delete the lines corresponding to the unwanted repository.

  • You can also edit out the line in /etc/apt/sources.list by using # In case you want to re-use it later.

What worked for me:

  1. Check your /etc/apt/sources.list and remove unwanted sources.

    sudo nano /etc/apt/sources.list

  2. If step 1 does not solve your problem, see what other sources are used:

    sudo ls -al /etc/apt/sources.list.d/

  3. If you have found a source-list causing the problem, remove it (in the example below, NodeJS source list is removed):

    sudo rm /etc/apt/sources.list.d/nodesource.list

OK THis is major: If you are unable to download the Pi2 version, edit (Nano) the list file(s) in etc/apt/sources.list.d folder. THere will be an line YOU MUST CHANGE to get the files into your repository. "arch=amd64" MUST BE CHANGED TO "arch=armhf". THen check the repository list with "sudo apt-cache policy AppNameHere". If you dont have the names of the downloads, you've done it wrong.
