Debian 拉伸包系統在添加非免費時中斷
在具有 4G 記憶體、500G HD 和 Intel® Core™ i3 CPU M 330 @ 2.13GHz × 4 的 HP G62-144DX 上全新安裝 SMP Debian 4.9.30-2+deb9u2 (2017-06-26) x86_64 GNU/Linux一切正常。我已經更新了 apt 儲存庫幾次以確保沒有更新，所以在我嘗試添加非免費之前我知道它正在工作。
在 synaptic apt 中選擇“DFSG-compatible Softeare with Non-Free Dependencies (contrib)”後變得“不開心”。我曾嘗試尋找答案，但要麼在錯誤的地方，要麼就是我自己（即墨菲定律）。
當呼叫 apt-get update 時，我得到以下資訊：

據我所知，apt-key 擁有 update 所抱怨的所有鍵。以下是我能想到的相關輸出：

有人能告訴我我錯過了什麼嗎？我剩下的頭髮很少，一次撕掉一把也無助於回答問題或改善我的外表。
為每個請求添加了 df -h

在我使用發行版安裝程序安裝的全新 debian 9 上也存在同樣的問題。在將trusted.gpg 文件移開後，問題就消失了：
sudo mv trusted.gpg trusted.gpg-broken之後apt似乎很高興。我也是 ！
