Package conflict errors with ea-nginx on CloudLinux

by | May 8, 2021

Stuck with Package conflict errors with ea-nginx on CloudLinux? We can help you.

Sometimes, yum or cPanel updates may fail with this error on Cloudlinux servers.

As part of our Server Management Services, we assist our customers with several CloudLinux queries.

Today, let us see how to effectively resolve this error.


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

Loaded plugins: fastestmirror, universal-hooks
Loading mirror speeds from cached hostfile
* cpanel-addons-production-feed:
* cpanel-plugins:
* epel: pub
Resolving Dependencies
–> Running transaction check
—> Package ea-nginx.x86_64 3:1.19.7-3.el7.cloudlinux will be inst

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




CloudLinux has come up with a patch to this issue that is currently in beta testing:

To fix systems that experience this error currently, we 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, we install it:

# yum install ea-nginx –enablerepo=cl-ea4-testing
