In my case it has been a misconfigurated file in /etc/nginx/sites-enabled/ I named them as .old files, but that does not matter. They will be readed and may prevend an successfull installation or start of that service. Be careful with files in that folder and read your error output carefully as discribed by @Taiger
I see you want to reinstall Nginx, but we can have the same error when we have Nginx run in Docker container.
In this case, just look at started containers:
user@host:~$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES f4ee2264d5fb docker_nginx "nginx -g 'daemon of…" 5 months ago Up 2 days 0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp nginx
Just stop it with CONTAINER ID
docker stop f4ee2264d5fb
Then you are able to install Nginx
