Cannot install Proxmox - Network issues

[FlorinMarian]

Hi guys!
I've tried today to install latest 3 versions of Proxmox on my HP ProLiant DL360e Gen8 but none succeed.
All of them answer to me on White Background "No network interface found".
What's strange?
I already have Proxmox 5.5 which I would like to erase and there my network connection working fine (ens1, motherboard slot).
Any solution?
Thank you!

Proxmox 5.5

which version do you mean exactly (the latest PVE 5 version is 5.4)?

Apart from that you can upgrade a PVE 5.x to 6.x in-place : https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0
You can also install PVE 6.x on top of a fresh installation of debian buster : https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_install_proxmox_ve_on_debian

If you want to further debug the installer you can start it in Debug mode - this should drop you into a shell at various points of the installation - check the output of `dmesg` for potential problems - also the output of `ip link` and `ip addr` in those shells would be of interest

hope this helps!
