Ubuntu
apt-get unmet dependencies，傳統解決方案不起作用
問題
採取任何將更改我的 Ubuntu 12.04 LTS 伺服器上已安裝軟體包的操作（刪除、安裝、清除等）都會失敗，並顯示：

我幾乎可以肯定最初的原因是完整的引導分區。但我現在已經通過
dpkg -ring 一些舊核心清除了這一點。apt-get removing在使用與上述類似的堆棧跟踪失敗後，我使用了此方法。問題的另一個潛在來源，雖然我認為不太可能，因為我看不到任何關係，是postgres 更新中的 Fsync 錯誤，我通過刪除證書的符號連結並按照說明直接複製證書來解決這個問題關聯。該錯誤與 apt-get 問題同時出現在我面前，所以我提到它是為了完整性，但正如我所說，我不知道它會如何破壞 apt-get。
我試過的
如前所述，我已經在引導中清除了一些空間。我試過
apt-get install -f了，這導致了我在上面發布的堆棧跟踪。我還嘗試編輯 dpkg 狀態文件並刪除 initramfs，但同樣沒有成功。我現在已經恢復到原始狀態文件。有誰知道我該如何解決這個問題？
您可以嘗試使用 dpkg 手動安裝單個軟體包（例如 dpkg -i /path/to/package.deb）。.debs 應該在 /var/cache/apt/archives/ 中。從 lib 包開始，尤其是 libssl-dev 和 libpq-dev。
在每個之後，再次嘗試 apt-get -f install 以查看是否已取消它。
