[SOLVED] Can't install proxmox (8.2 or 7.4)

[WoisWoi]

Hi,

I have tried to install Proxmox 8.2 in the first place, I got stuck at "loading drivers", then I tried to install the 7.4 version, and I got stuck at "Waiting for /dev to be fully populated..." then I've tried to modify the kernel bootline by adding "nomodeset" and I am now stuck after an audio error (when checking for errors it says "Fatal server error: (EE) cannont run in framebuffer mode. Please specify busIDs for all framebuffer devices"...

Any idea of what I could do (except installing debian on top...) ? What kind of information could you need to help me out ?

I'm running a memtest right now to make sure the RAM is not the issue (it's a brand new server). Also, I managed to install ubuntu server 24.04 without any problem.

Server specs :


Thanks you !

You probably need something like nomodeset (which seems to have helped in other threads on this forum) or try the new non-graphical installer of PVE 8.2 (or both).

Please be aware that the Crucial P3 uses QLC flash memory and might wear out quickly with Proxmox and be unusable slow when VMs write a lot. And it will definitely give problems if you use ZFS instead of LVM/ext4.

As I said I tried nomodeset, and I forgot to say but I tried both installer graphical and terminal when I was trying to install 8.2 (also tried with and without GPU card), since when I first tried I had a blackscreen after starting the installation.

A thought, perhaps also try to install a clean debian 12 bookwork, and see if that works.
If it doesn't, then there is a problem with debian vs ubuntu on your system/hardware.
If it does work, then that is strange, but you can also use the method of installing ProxMox on top of Debian 12 to proceed:

Well, my problem is solved.

I don't know why, but it seems that having a different OS already installed caused the problem (I had TrueNAS Core orUbuntu already installed when I was trying, note that I was planning to overwrite the OS, I wasn't trying to get a dual boot or something like that).

I installed debian easily, and then, the proxmox installer worked perfectly as intended...
