嘗試了 AskUbuntu 上其他幾個問題提供的解決方案，但沒有一個可以按如下所述工作。
在 Ubuntu 16.04.1 LTS 上，當我運行時
sudo apt update
我們得到以下錯誤。

~# mount -t ext4
/dev/vda1 on / type ext4 (ro,relatime,data=ordered)
怎麼了？有任何想法嗎？
答案1
我在 Ubuntu 18.04.4 上遇到了同樣的問題。
然後，我發現在目錄terminal上無法運行任何內容，因為目錄檔案系統是.我以為重新啟動可以解決問題，但我的電腦在重新啟動期間卡在了部分。我的主目錄安裝為 /dev/sda2 （以查看）。homehomeread-only(initramfs) _sudo fdisk -l
根據這我輸入的答案：
(initramfs) fsck /dev/sda2
然後：
(initramfs) reboot
這解決了我的問題，我可以跑步apt update和做其他事情。
筆記：此解決方案是一個臨時解決方案。如果我找到永久解決方案，我會通知您。
編輯：我找到了解決方案。如果您的磁碟有大量bad sectors.您必須忽略磁碟上的這些壞磁區。
