Empty File Using echo Command
# echo "" > access.log OR # echo > access.log
Note: You should keep in mind that an empty string is not the same as null. A string is already an object much as it may be empty while null simply means non-existence of an object.
For this reason, when you redirect the out of the echo command above into the file, and view the file contents using the cat command, is prints an empty line (empty string).
To send a null output to the file, use the flag -n which tells echo to not output the trailing newline that leads to the empty line produced in the previous command.
# echo -n "" > access.log
Another instance of Certbot is already running (Letsencrypt)
If it is not running, check whether there are .certbot.lock files in your system.
find / -type f -name ".certbot.lock"
If there are, you can remove them:
find / -type f -name ".certbot.lock" -exec rm {} \;
