Ubuntu 無法開機 例子
===

2019.06.18
參考資料：https://askubuntu.com/questions/697190/fsck-error-on-boot-dev-sda6-unexpected-inconsistency-run-fsck-manually

進到 emergency mode 之後，發現有行

/dev/sda3 contains a file system with errors, check forced.
/dev/sda3: Inodes that were part of a corrupted orphan linked list found.

/dev/sda3: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
        (i.e., without -a or -p options)
fsck exited with status code 4
The root filesystem on /dev/sda3 requires a manual fsck

，依照參考資料，執行 `fsck /dev/sda3` ，然後一直按y，好了之後就打`exit`，然後就可以正常開機了。
過程中還以為是nvidia的問題，因為進到 emergency mode 之前看到的最後的錯誤訊息是 `PKCS#7 signature not signed with a trusted key` ，所以很容易誤會。
說不定我上次的ubuntu 18.04也是同樣的問題，只是那時候沒有找到解決方法，所以就重灌成19.04了。
