CentOS 7 EOL Information

CentOS 7 officially reached EOL status this past Sunday (June 30th): What to know about CentOS Linux EOL.

When an OS goes EOL, it shuts down its repos and mirrors. Servers will start to report errors like the following:

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=genclo error was

Trying other mirror.
It was impossible to connect to the CentOS servers.
This could mean a connectivity issue in your environment, such as the requirement to configure a proxy,
or a transparent proxy that tampers with TLS security, or an incorrect system clock.
You can try to solve this issue by using the instructions on https://wiki.centos.org/yum-errors
If above article doesn't help to resolve this issue please use https://bugs.centos.org/.

This means that your server will no longer receive any updates from non-InterWorx packages, including security updates.

Regarding InterWorx, we released a hotfix yesterday that will allow InterWorx updates to continue for the time being on CentOS 7 servers.

To check if you have the hotfix:

  1. Log in to the server at the CLI as root, either via SSH or from the terminal
  2. Check the InterWorx version:

rpm -q interworx

  1. Check the interworx-hotfix version:

rpm -q interworx-hotfix

The hotfixes for each currently supported InterWorx version are as follows:


If your server does not have the corresponding hotfix, please run:

yum clean all
yum --disablerepo "*" --enablerepo interworx-hotfix install interworx-hotfix

Again, though, that only will address InterWorx updates. You may continue to receive errors related to OS-level packages, including yum failure emails.

It is strongly recommended to migrate to a server with a supported OS.

It is not possible to do an in-place upgrade from EL7 to EL8. InterWorx must be installed on a new, fresh, minimal EL8 install.

InterWorx 7 is currently supported on RHEL 8, Alma Linux 8, and Rocky Linux 8: What are the system requirements of InterWorx Control Panel? — InterWorx documentation

EL9 support is currently in public beta, however, it is not recommended, yet, for production servers: https://forums.interworx.com/t/interworx-8-public-beta-and-el9-support/.

Also, please note, InterWorx 6 severs 100% will need to migrate to a new server with a supported OS and IW version. It is now no longer possible, at all, to update to IW7. Our support for IW6 went EOL last Sept.

If you would like a demo key to facilitate the migration, just submit a ticket to support.interworx.com and let us know. :slight_smile:
