Updating a Proxmox VE Host/Node

  • Migrate all Guests to other nodes in the cluster
  • Do an apt update to check how many packages require updating
  • Do a download-only upgrade apt dist-upgrade --fix-broken --fix-missing -d -y
  • Upgrade the node: apt dist-upgrade --fix-broken --fix-missing
  • Reboot
  • Once the node reboots check that all NIC Devices have the same names and have not changed.
  • Re-migrate guests
