    This is part of a known upstream issue when using the Unofficial testing repository home_Jperkster_ea-freetds There is a workaround which is as follows: At the moment, the workaround involves removing Apache along with the modules that have been installed as part of the "home_Jperkster_ea-freetds" repository. Usually performing a 'yum remove ea-apache24' should handle the removal of all of the modules, however some situations may require some more intervention, for example some servers will require 'ea-apache24-tools' to be removed separately. Create staging directory and download profile mkdir -vp /root/staging && ea_current_to_profile --output=$_/current.profile
    Remove Apache and the additional tools package yum remove ea-apache24 ea-apache24-tools
    Disable the unsupported repository yum-config-manager --disable home_Jperkster_ea-freetds
    Use the EA4 profile to reinstall their packages from the official sources awk -F '"' '/ea-apache/{printf $2" "}' /root/staging/current.profile | xargs yum -y install
    Update virtfs so that users can access PHP sessions again /scripts/clear_orphaned_virtfs_mounts --clearall /scripts/update_users_jail /scripts/restartsrv_httpd --hard

    I got same issue. It happened just after cpanel upcp cronjob. I did not enable any auto update or any 3rd party yum. This is ridiculous, this is not the 1st time cpanel upcp cronjob causing this issue within this 2 years and there's no way to prevent cpanel nightly cronjob to cause the problem.

    Hello /usr/local/apache/bin/httpd: symbol lookup error: /usr/local/apache/bin/httpd: undefined symbol: apr_atomic_read64 The httpd not restart and return this error. Can someone help me?

    If you're getting the same error @garconcn you would have had to have enabled this 3rd party repository and the steps shown to resolve it should work for you. We can confirm this by checking your repositories in /etc/yum.repos.d/ or looking at the error when you attempt to update/reinstall apache: yum reinstall ea-apache24

    I've not encountered that before. Are you still on EA3?

    RPMUP was set to manual, why cpanel still do YUM update? # cat /etc/cpupdate.conf CPANEL=stable RPMUP=manual SARULESUP=never STAGING_DIR=/usr/local/cpanel UPDATES=manual

    Hello @garconcn You don't have the repo in question here so the issue is not the same. Please show the output of the error you're receiving so we can assist you with resolving it.
    RPMUP was set to manual, why cpanel still do YUM update?

    I would suggest you read the documentation on this here: Update Preferences - Version 80 Documentation - cPanel Documentation Specifically: [QUOTE] Notes:
    • This setting does not impact cPanel-provided RPMs.
    • In cPanel & WHM version 68 and later, the /usr/local/cpanel/scripts/sysup script automatically updates the EasyApache 4 RPMs. The following settings will not prevent an automatic update:
      • The RPMUP variable set to never in the /etc/cpupdate.conf file.
      • The Operating System Package set to Never Update in WHM's Update Preferences interface (WHM >> Home >> Server Configuration >> Update Preferences).
    • You can prevent the /usr/local/cpanel/scripts/upcp script from creating new EasyApache 4 yum repositories if they don't already exist. To do this, use the touch command to create the the /var/cpanel/skip-repo-setup file. For example: touch /var/cpanel/skip-repo-setup
