"It’s also possible to install Proxmox VE 9.0 on top of Debian."

Has that always been the case? I have a faint memory of trying once and not being able to with Proxmox 7.x

[robeastham]

I'm pretty sure it's been the case since at least 7.0, as I've done it a few times on hosts such as Scaleway that only offered a Debian base image for my machine.

You can even install Proxmox on NixOS now (no official support ofc) though https://github.com/SaumonNet/proxmox-nixos

Which I think is really cool since it means their stuff is "truly open-source" :)

I wonder about things like this.

It seems to me people who try things like this might also be ok with spaces in filenames, or replacing bash with csh...

It should work, but you might want to cross your fingers.

Yes it's always been the case. I installed Proxmox 3.4 (based on Debian 7) this way originally, and have been upgrading ever since with no issues.

We did it for 7.x [1] and it worked fine (since upgraded things in-place to 8.x).

I just installed 9.0 atop Trixie. Works fine, just follow https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12... and replace the distro name.

Somewhat annoyingly, Proxmox relies on a non-Debian kernel for at least some of its features. This definitely made a difference w/ Bookworm (which was on the 6.1 kernel release series), not sure about Trixie (which will be on 6.12).

Yeh. It's useful when trying to install onto partition setups the built in installer doesn't support OOTB.

But, things like proxmox-boot-tool may not work.

[rcarmo]

I've done it a few times--8.x for sure, maybe earlier, but I've now been using it for too long to remember accurately.

[oakwhiz]

I do it this way every time.
