N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

I have tried below links, but nothing worked. apt- sudo apt-get update not working! "sudo apt-get update" is not working

Please help me in resolving the error!


You can change the repository that figures there


,that dont have a release file for this one:


If that doesn't work, you should delete that repository, i tried to enter there and i found that it donest exist anymore(the version is no longer supported), sor you could try the 18.04 or delete the first

You can search a way to add repositories searching on google how do that for you SO(i think that is Xubuntu 16.04)

  • Yes, both of the repositories don't exist. I tried to remove the repository(Software & update > Other Software > Select the link > Remove > Close) in the error i.e., download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04 and it solved the problem. Hence, sudo apt-get update is running fine now. But I am thinking how do I know which repositories should be added to that list. Are there any standards/ general repos? – Brijesh Apr 3 '20 at 7:15
  • Yes, there are "official" repositories for each distribution, and they would have "mirrors" from different contries. I suggest you search in google mirrors that are near to your country(.in is from india i think), and try to get them. I give here an example of some US. mirros, and a description that gives you some idea of the structure of the type of repositories you will find: gist.github.com/rhuancarlos/c4d3c0cf4550db5326dca8edf1e76800 – Munsko Apr 3 '20 at 10:34
