  pveam download local ubuntu-22.04-standard_22.04-1_amd64.tar.gz
  pveam download local ubuntu-24.04-standard_24.04-1_amd64.tar.zst

  Once downloaded, these templates can be used to create new LXC containers from the Proxmox web interface or via CLI.

  If your disk is using SCSI instead of virtio, resize like this:
