Bug#1123551: installation-reports: Static IP correction during install is not persisted to final system
Package: installation-reports
Version: Debian 13.2 (Trixie)
Severity: normal
-- Information about the install --
Method: Network installation (netinst) via ISO
Date: 2025-12-17
Machine: Virtual Machine (xcp-ng)
-- Issue Description --
I encountered an issue where the Debian Installer (d-i) persisted an
incorrect initial network configuration despite my correcting it
during the installation steps.
Steps to reproduce:
1. Booted the Debian 13 Testing installer.
2. During the network configuration step, I manually configured a
Static IP address. I accidentally entered an incorrect/non-working IP
address.
3. The installer proceeded to the "Configure the package manager"
(mirror selection) step.
4. Because the IP was incorrect, the mirror connectivity check failed.
5. I used the installer menu to go back to the Network Configuration step.
6. I corrected the Static IP to a valid, working address.
7. The mirror selection step then passed successfully, and the
installation completed.
8. Upon the first reboot of the installed system, the server came up
using the INITIAL (bad) IP address, not the corrected one used to
complete the installation.
Expected Behavior:
The final /etc/network/interfaces (or NetworkManager config) should
reflect the corrected IP address that was successfully used to
download packages.
Actual Behavior:
The system reverted to the first user input provided, ignoring the
subsequent correction made during the install session.
