I'm running Plesk 12.0.18. Anyone stumbled upon this before? Is there a workaround? Do i have to wait for an update?

Try to fix it with something like:

sudo apt-get update
sudo apt-get purge sw-nginx
sudo apt-get install sw-nginx

Thank you for your help. The issue was that i installed nginx by command line before. Unfortunatly i haven't uninstalled all nginx parts (only 1) before i tried to install it by plesk.

these commands helped me to find the other nginx-packages

sudo apt-get install aptitude
aptitude -F' * %p -> %d ' --no-gui --disable-columns search '?and(~i,!?section(libs), !?section(kernel), !?section(devel))'
