I'm trying to fix this issue when running
sudo apt update:
E: The repository 'https://download.docker.com/linux/ubuntu loki Release' does not have a Release file. 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 tried adding the correct repository:
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu \ xenial \ stable"
Also tried searching for the "loki" keyword and replace to "xenial", no luck:
lucaswxp@imhuman:/etc/apt/sources.list.d$ cat * | grep "loki" > empty result
Any idea how to get apt update to work again?
