Specifically on Proxmox and Houston, I was able to successfully setup the repo’s from 45Drives and install their cockpit modules on Proxmox 8.2 which is still latest the major/minor release. I just had one extra step to get it to work.
It’s just needs to be known that it’s not officially supported on Proxmox or Debian Bookworm. I’m still hoping that will change with the next version of Houston that 45Drives has been actively developing.
Also, Proxmox w/ Houston is not my daily driver on my HL15 so I can’t say my validations were super robust or all encompassing. My HL15 is on TrueNAS Scale Dragonfish. I do have Rocky 8 and Houston on the original NVME drive in case I ever wanted to check it out again.
