YUM encountered errors outside of EasyApache 4

In this guide, i will show you how you can fix the EasyApache4 yum error after installation of imunify360 or cloudlinux. some time php error.

# ll /etc/yum.repos.d

• If the system is registered to RHN Classic, only rhel-source.repo should be present under /etc/yum.repos.d/.
  If the system is registered with Red Hat Subscription Manager (RHSM) via subscription-manager, rhel-source.repo and ‘redhat.repo’ are present.
  If any local repositories, or any other media repositories are present, remove them by :-

Raw

# rm -rf /etc/yum.repos.d/<local or other repository name>

• Remove old yum cache from system by running following commands:

Raw

# rm -fr /var/cache/yum/*
# yum clean all

• Check if you can list the valid repositories by :-

Raw

# yum repolist

If you are using subscription-manager and the previous solutions do not work, try reenabling each repository one-by-one with the following:-Raw

# REPOLIST=`subscription-manager repos --list-enabled | grep "Repo ID" | awk '{print $3}'`
# subscription-manager repos --disable="*"
# rm -fr /var/cache/yum/*
# yum clean all
# for i in ${REPOLIST}; do subscription-manager repos --enable=$i ; yum repolist; done

Root Cause

• Possible reasons for this issue:
  1. Corrupted yum cache.
  2. Inaccessibility of a repository URL from the system due to network related issues.
  3. Presence of customized or other media repositories.
  4. Outdated whitelist when using IP-based Firewall configuration to access
