php-fpm 檢測到不安全的路徑轉換錯誤消息。如何？

我對 linux/ubuntu 知之甚少，但我需要它來執行我想要執行的網路伺服器。我已經完成了所有設置並且執行良好，而且我已經有一段時間了。每次我嘗試使用 apt 安裝某些東西時，都會收到此錯誤。看過類似的文章，都建議建個文件夾嘗試啟動服務，但每次都得到相同的結果。

我嘗試過的一些文章/事情：

• https://stackoverflow.com/questions/29859131/unable-to-bind-listening-socket-for-address-php-fpm
• sudo apt 重新安裝 php-fpm

此錯誤消息確定了根本原因：

Detected unsafe path transition / → /run during canonicalization of /run.

當您系統的根目錄/擁有錯誤的所有權或權限時，就會發生這種情況。

要解決此問題，請更正所有權和權限。

sudo chown root /
sudo chgrp root /
sudo chmod u=rwx,go=rx /

修復此問題後，您可以修復部分安裝的軟體包。

sudo apt -f install

然後繼續討論您的下一個問題。
