Ubuntu中的這種依賴升級安全嗎？

我想在執行 Ubuntu 12.04 LTS 的內部生產伺服器上安裝 PHP5。當我嘗試使用apt-get它來安裝它時，它會列出大量依賴項並建議執行apt-get -f install. 當我執行它時，我得到了這個返回：

這是在生產機器上進行的安全升級嗎？我知道apt-get dist-upgrade可能非常重要並且會破壞事情。這是小升級還是大升級？

謝謝

分區已滿，/boot不允許我執行apt-get -f install。嘗試從 ubuntugenius 執行此腳本時，dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge我得到以下資訊：

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-headers-server : Depends: linux-headers-3.2.0-59-generic but it is not going to be installed
linux-server : Depends: linux-headers-server (= 3.2.0.37.44) but 3.2.0.59.70 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

我覺得我現在陷入了一個循環，充滿/boot了不會讓我執行修復，但我無法/boot在不執行修復的情況下清除。

我已經成功清除了一些空間，/boot直到現在才得到以下錯誤：

apt-get -f install是修復操作。因此，您的系統目前存在一些問題，這是要修復的。

我的猜測是，如果您現在還沒有安裝核心，那麼您真的需要這樣做，因為您現在的系統甚至可能無法啟動！

這只是一個可用的核心升級。您可以毫無問題地更新。重新啟動後，它將載入新核心。如果確實發生了某些事情，您可以在引導載入程序中選擇較舊的核心並解除安裝最新的核心。
