From ae3d5a5515fcae7455ad3b50619ec7e8a4bc16c8 Mon Sep 17 00:00:00 2001

Date: Wed, 3 Sep 2025 17:43:58 +0530
Subject: [PATCH] fix(apt): ensure Bruno repo key is world-readable on Debian
 12+ (#5474)

- Added `chmod 644 /etc/apt/keyrings/bruno.gpg` so `_apt` user can read the key
- Keeps key in binary format with `gpg --dearmor`
- Prevents NO_PUBKEY errors and repository being ignored on Debian 12+
