9.4. Operating Systems
- Section last updated:
2026-04-02
This section outlines the Linux operating systems compatible with LOCKSS 2.0-beta2 NOT YET RELEASED.
As outlined in the System Prerequisites, LOCKSS 2.0-beta2 NOT YET RELEASED requires a 64-bit Linux host [1] compatible with K3s, a lightweight open source Kubernetes distribution. The K3s documentation states that "K3s is expected to work on most modern Linux systems", and that "Some OSs have additional setup requirements" [2] (which are documented in this manual and integrated into the LOCKSS Installer).
9.4.1. Compatible Operating Systems
LOCKSS 2.0-beta2 NOT YET RELEASED is compatible with the following Linux distributions. Note that it can likely be installed successfully on additional Linux distributions not listed here; we welcome reports of successful installations from the community so they can be added to the list below.
Tip
If you or your IT department do not have a strong preference in terms of Linux distribution, we recommend community-supported RHEL alternatives AlmaLinux OS and Rocky Linux.
AlmaLinux OS
LOCKSS 2.0-beta2 NOT YET RELEASED is compatible with AlmaLinux OS.
AlmaLinux OS is suitable for a same-host migration from LOCKSS 1.x to LOCKSS 2.x [3].

9.4.2. Unsuitable Operating Systems
The following operating systems are not suitable for use with LOCKSS 2.0-beta2 NOT YET RELEASED because they are at end of life.
CentOS Linux end of life
Warning
CentOS Linux is at end of life and is not suitable for use with LOCKSS 2.x.
Tip
If you are currently running LOCKSS 1.x on a CentOS Linux host, we recommend a new-host migration to LOCKSS 2.x. However, if you perform a same-host migration to LOCKSS 2.x, you must upgrade your host to a newer operating system in the RHEL family first, such as Rocky Linux, AlmaLinux OS, Oracle Linux, or Red Hat Enterprise Linux (RHEL). See OS Upgrades in the LOCKSS Community Wiki for guidance.
