Raspberry Pi port of Proxmox

Somebody did it :)

Yes, Proxmox Devs spent quite some time on this in 2018, for example a few commits here:

etc..

So, as the sources got support already a few years ago to be ready for that, it should be a plain re-build.

We decided against providing official packages as at that time no server HW was available, we only got our applied-micro based evaluation board by working together with a partner of ours (shout out to Thomas Krenn), and that was really slow. I.e., while stating to provide high-end performance it would be easily beaten by any x86 platforms with fewer cores we had around.

Take care and be wary when adding external repositories - you place the full trust in the ones having access to create those.
 
Somebody did it :) Also can be useful as a quorum host in an adult 2 nodes cluster. Here
Tried to install it on a rpi4 (5.10.0-0.bpo.5-arm64) but got the following error:

Code:
The following packages have unmet dependencies:
 pve-manager : Depends: libjs-extjs (>= 6.0.1) but 3.4.0+dfsg1-1 is to be installed
