Original GitHub issue: https://github.com/community-scripts/ProxmoxVE/issues/10004

✅ Have you read and understood the above guidelines?

Yes

🔎 Did you run the script with verbose mode enabled?

Yes, verbose mode was enabled and the output is included below

📜 What is the name of the script you are using?

pve-scripts-local.sh

📂 What was the exact command used to execute the script?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/pve-scripts-local.sh)"

⚙️ What settings are you using?

Default Settings
Advanced Settings

🖥️ Which Linux distribution are you using?

Debian 13

📈 Which Proxmox version are you on?

pve-manager/8.4.1/2a5fa54a8503f96d (running kernel: 6.8.12-11-pve)

📝 Provide a clear and concise description of the issue.

Script in default mode assumes vmbr0 exists, and attempts to install on that network.

The networks on this server happen to have the vmbr's renamed to number in alignment with the eth* ports, so there is no vmbr0

The script should check for this first, and recommend switching to advanced mode, which does support selecting which bridge vmbr* for the management network.

🔄 Steps to reproduce the issue.

Run this script as above, the default instructions - download & run in one liner.

Note how to run this script in verbose mode is not easily found, does it exist?

Choose default, choose storage, go!

See the error below.

❌ Paste the full error output (if available).

No, for such Special cases are the advanced Settings where you can choose your Bridge. Thats a case of 0,005% of all Installs. You can use the User defaults for this. We cannot handle thousands of cases for every user. Vmbr handle 99,9995 % of all Installs
