Proxmox PVE 9 Server Installation mit Debian 13 (Trixie) Unterbau

Post by h3rb3rn »

Fassung vom 30.12.2025

Voraussetzung: Debian 13 (Trixie) Minimal Installation, Root-Zugriff.

Relevante Änderungen in Debian 13 / PVE 9: ---

Option A: Auto-Installer (1-Line)

Führt Netzwerkmigration, Repo-Setup und Installation automatisch durch.

Code: Select all

bash <(curl -s -L https://4noobs.de/download/file.php?id=255)
---

Option B: Manuelle Installation

1. Netzwerk Migration
Wir installieren `ifupdown2`. Falls Netplan vorhanden ist, sichern wir die Configs weg.

Code: Select all

apt install ifupdown2
mkdir -p /root/netplan_bkp && mv /etc/netplan/*.yaml /root/netplan_bkp/ 2>/dev/null
Erstellen der Bridge in `/etc/network/interfaces` (Interface Namen eno1 anpassen!):

Code: Select all

auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.10/24
gateway 192.168.1.1
bridge-ports eno1
bridge-stp off
bridge-fd 0
Wichtig: Nach dem Speichern `pkill dhclient` ausführen, falls der DHCP-Client das Interface blockiert.

2. Hostname (/etc/hosts)
Die IP muss dem Hostnamen zugewiesen sein, nicht 127.0.1.1.

Code: Select all

127.0.0.1       localhost
192.168.1.10    pve-node.local pve-node

# 127.0.1.1     pve-node  <-- Diese Zeile entfernen!

3. Repositories (DEB822)

Code: Select all

mkdir -p /etc/apt/keyrings
wget -qO - [https://enterprise.proxmox.com/debian/proxmox-release-trixie.gpg](https://www.google.com/url?sa=E&source=gmail&q=https://enterprise.proxmox.com/debian/proxmox-release-trixie.gpg) > /etc/apt/keyrings/proxmox-release-trixie.gpg

cat > /etc/apt/sources.list.d/pve-install.sources <<EOF
Types: deb
URIs: [http://download.proxmox.com/debian/pve](http://download.proxmox.com/debian/pve)
Suites: trixie
Components: pve-no-subscription
Signed-By: /etc/apt/keyrings/proxmox-release-trixie.gpg
EOF
4. Installation

Code: Select all

apt update && apt full-upgrade -y
apt install -y proxmox-ve postfix open-iscsi chrony
5. Cleanup (Enterprise Repos)
Entfernt Enterprise-Quellen (Liste & DEB822) um 401 Fehler zu vermeiden.

Code: Select all

rm -f /etc/apt/sources.list.d/pve-enterprise.sources
rm -f /etc/apt/sources.list.d/pve-enterprise.list
apt update
apt remove -y os-prober
6. Reboot
