Ubuntu 20.04 Curated Images - End of Life (EOL)​

Canonical, the maker of Ubuntu, has announced EOL of Ubuntu 20.04 effective May 31st, 2025.

For Crusoe customers currently using a curated image based on Ubuntu 20.04:

  1. Image availability. You can continue using your Ubuntu 20.04 VMs after May 31st, 2025 at your own risk.
  2. End of Support. Crusoe Cloud will no longer be supporting or releasing new curated images based on Ubuntu 20.04.
  3. Image deprecation. Ubuntu 20.04 will remain as a curated image option on Crusoe Cloud until November 3rd, 2025 but its use is not recommended without an ESM license which can be purchased from Canonical.

Recommendations:

  1. Extended Security Maintenance (ESM) Support: If you require continued use of Ubuntu 20.04, you can purchase ESM support licenses from Canonical to continue receiving extended security updates.
  2. VM Migration: You can create a new VM based on Ubuntu 22.04 or later and migrate your workload to the new VM.

Crusoe CSI driver v0.4.11 and earlier — End of Life (EOL)​

Crusoe CSI driver versions earlier than v0.4.12 are deprecated and will become unsupported after November 8, 2026. After this date, clusters with older CSI drivers may begin to experience shared disk mount failures as Crusoe rolls out file storage platform changes, and Crusoe will no longer provide support for mount issues on unsupported driver versions. Clusters running in a private network without outbound internet access must upgrade before then.

CMK clusters that mount shared disks through the Crusoe CSI driver (fs.csi.crusoe.ai) should upgrade to CSI driver v0.4.12 or later (Helm chart 0.10.21+)

Starting with v0.4.12, the CSI driver resolves the NFS storage hostname itself and passes explicit IP addresses to the kernel NFS client, so mounts no longer depend on the node's DNS configuration. If in-driver resolution fails for any reason, the driver falls back to the previous behavior and lets the kernel resolve the hostname, so the upgrade introduces no new failure mode.

For Crusoe Managed Kubernetes (CMK) clusters mounting shared disks through the CSI driver (fs.csi.crusoe.ai):

  • Driver incompatibility: Crusoe CSI driver versions earlier than v0.4.12 are deprecated. After November 8, 2026, these versions are unsupported.

Recommendations:

  • Verify affected clusters: Check your CMK clusters to confirm whether they use fs.csi.crusoe.ai for shared disk mounts. Only those clusters are affected by this change.
