Good afternoon. I performed a fresh installation only to reproduce the issue. Steps: - Today, 24/11/2025 at 06:00, I flashed the Debian 13 64-bit system onto the SD card using rpi-image. - Updated the system: sudo apt update && sudo apt upgrade -y - Rebooted. - System working normally with autologin. Ran another update: sudo apt update && sudo apt upgrade -y && sudo apt autoremove -y - Rebooted. - System still normal with autologin. Then I ran: sudo apt remove gnome-keyring - Rebooted. - System no longer performed autologin and the correct password failed on the graphical login screen. - Logged in through SSH. - Installed reportbug: sudo apt update && sudo apt install reportbug and configured it. I collected the requested files and some additional ones. I also forgot to mention that about 7 days ago this same problem occurred on two other Raspberry Pi 4 systems. I performed several tests at the time (for a personal project), and during those tests the same login failure appeared, but I hadn’t used sudo apt remove gnome-keyring on those systems. Since I could not understand the cause and could not reproduce the issue, I reinstalled the system on both.
