Shutting down apache2 first before installing nginx should fix this problem:
sudo service apache2 stop
Andrew Chan provided the right answer for me. To extend his answer a bit, here's what you can do on the commandline;
sudo systemctl stop apache2.service
prevent apache2 to start at boot
sudo systemctl disable apache2.service
sudo apt-get install nginx
I just had this issue, but the solution was slightly different.
Once I solved a simple site misconfiguration, I was able to update nginx.
Check your nginx error log:
sudo cat /var/log/nginx/error.log|less
Then try again:
sudo apt-get update;sudo apt-get upgrade
In my case the error is the server has IPv6 disabled. Solution:
/etc/nginx/sites-enabled/default and comment IPv6 out:
listen [::]:80 default_server;
apt purge nginx apt autoremove apt install nginx
When I checked /var/log/nginx/error.log I saw that the installer was unable to open /var/cache/nginx/microcache
A directory listing showed there was no /var/cache/nginx directory, so I created it and the install succeeded.
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
Before the installation remove any manually added symlinks from
