Nature of Package conflict errors with ea-nginx on CloudLinux 

Generally, in Cloudlinux servers with ea-nginx, yum or cPanel updates tend to fail with the error:

# yum update

Error: ea-modsec30 conflicts with 2:ea-apache24-mod_security2-2.9.3-4.el7.cloudlinux.x86_64
Error: ea-apache24-mod_security2 conflicts with 1:ea-modsec30-3.0.4-6.el7.cloudlinux.x86_64
You could try using –skip-broken to work around the problem.


In addition, the installation of ea-nginx on a server with ModSecurity2 packages fails with the same error.

On Cloudlinux servers since we already have packages for ModSecurity2, trying to install ea-nginx or run a yum update/cPanel update fails.

Because, as a part of ea-nginx dependencies, some of the ModSecurity3 packages will also attempt to install.

This causes a conflict between the packages belonging to ModSecuirty2 and Modsecurity3, which in turn causes yum and UPCP to fail.

To confirm that ea-modsec30* packages are being pulled because they are among the dependencies of ea-nginx, we run the following command:

# repoquery -R —resolve —recursive ea-nginx | grep -Ei sec
ea-modsec30
ea-modsec30-connector-nginx

Conclusion

This article covers how to resolve Package conflict errors with ea-nginx on CloudLinux. Basically, Cloudlinux servers with ea-nginx, yum or cPanel updates tend to fall with this error. 


On Cloudlinux servers where already packages for ModSecurity2 are installed (ea-modsec-sdbm-util & ea-apache24-mod_security2), trying to install ea-nginx or run a yum update/cPanel update fails because as a part of ea-nginx dependencies, some of ModSecurity3 packages (ea-modsec30 & ea-modsec30-connector-nginx) will also be attempted to be installed, and that causes a conflict between the packages belonging to ModSecuirty2 and Modsecurity3, which in turn causes yum and UPCP to fail. 


To resolve systems that are currently experiencing this error, update EA packages to the beta branch:

$ yum update ea-* --enablerepo=cl-ea4-testing

 

To install ea-nginx on affected systems using the beta repository, install it with the following command:

$ yum install ea-nginx --enablerepo=cl-ea4-testing
