nginx-light (< 1.14.0-0ubuntu1.2.1~) but it is not going to be installed or
nginx-extras (< 1.14.0-0ubuntu1.2.1~) but it is not going to be installed
Cause
Dependency conflict between the Plesk ‘sw-nginx’ package and 3rd-party nginx packages.
Resolution
-
Connect to the Plesk server via SSH.
-
Remove all 3rd-party nginx packages that are mentioned in the error message:
# dpkg -r package1 package2 package3 …
-
For example, based on the error message above, the following packages should be removed:
# dpkg -r libnginx-mod-http-geoip libnginx-mod-http-image-filter libnginx-mod-http-xslt-filter libnginx-mod-mail libnginx-mod-stream nginx nginx-full nginx-extras nginx-core nginx-light nginx-extras
If the packages fail to be removed using the command above, purge them with the command:
# dpkg -P –force-depends package1 package2 package3 …
-
-
Verify that only the ‘sw-nginx’ package is installed:
# dpkg -l | grep nginx
ii sw-nginx
