Package: debian-installer-12-netboot-amd64 Version: 12.7.0 (iso version) During installation, at the step to configure the package manager, the input field for the proxy do not properly register changes made using the mouse. When editing the field and moving the cursor with the mouse, the displayed input do not match the actual proxy string used by the system (and logged in syslog). To resolve this, clear the entire field and enter the proxy address again without making any corrections.
