I was googling out steps to update MySQL from 5 to 8 version. Without further thinking I inserted these commands in terminal:

sudo apt-key adv --keyserver keyserver.ubuntu.com

The keyserver of Ubuntu 12 version was added. So later I manually removed them from the "Other Software" tab of "Software and Updates".

Somehow it got better, but whenever I insert the command sudo apt-get update, it ends with the below-given error:

N: See apt-secure(8) manpage for repository creation and user configuration details

Terminal when sudo apt-get update was inserted:

I'm still not able to find a solution. Can anyone help?

  • I found the solution. I reset all the links using [Ubuntu Sources Link Generator](https://repogen.simplylinux.ch/). I referred to this [solution](https://askubuntu.com/questions/948607/ubuntu-17-04-update-issue) (which I was not able to find it earlier) – HV Sharma Jun 25 '19 at 06:22
