Hi i'm new to Linux and I need to use it temporary to set up LetsEncrypt. Once complete, I needed to move the /etc/letsencrypt/live/fullchain.pem file into the root dir but i moved the file incorectly: mv fullchain.pem /fullchain and then it showed up in my root as red fule fullchain so : mv fullchain fullchain.pem and something gone totally wrong. It appears to be a shortcut. The old file is gone.How can I rescue the file or get it back? Is the permission wrong? because the live folder is totally not accessible true the file browser but accessible true term with sudo -i
File -> ../../archive/folder/file restore
files;symlink;mv
Your file stills there. You only changed the file's path and name since you only execute mv and not rm command. Your original file must be in /fullchain.pem. You moved the fullchain.pem file from its original path /etc/letsencrypt/live/fullchain.pem to / that's why you can't see it any more in the main.Just execute $ mv /fullchain.pem /etc/letsencrypt/live/
