不幸的是，你的假設是錯的。讓我為您解讀這則訊息。

這是一個服務留言告訴您 OpenSSL 有安全性更新。這不是一個錯誤,警告或類似的東西。

由於有 4 個軟體包被保留，並且沒有一個軟體包需要升級，因此顯然 OpenSSL 已經升級到最新版本。
如果你運行apt policy openssl你會得到：
openssl:
Installed: 3.0.2-0ubuntu1.10
Candidate: 3.0.2-0ubuntu1.10
Version table:
...
這是最新升級版本（截至 2023 年 8 月）。
apt訊息只是一種服務，稱為「APT新聞」。要刪除這些訊息，請參閱此問答。
答案2
這對我來說仍然會出現。如果您知道修補版本（3.0.2-0ubuntu1.10），您可以使用以下命令檢查您安裝的版本apt list openssl：
openssl/jammy-security,jammy-updates,now 3.0.2-0ubuntu1.10 amd64 [installed]
當我運行時，我無法讓警告消失sudo apt upgrade，但您可以運行sudo pro fix CVE-2023-2650來檢查是否有任何其他易受攻擊的軟體包：
CVE-2023-2650: OpenSSL vulnerability

No affected source packages are installed.
✔ CVE-2023-2650 does not affect your system.
