Fix 'UNEXPECTED INCONSISTENCY; Run fsck manually' on Ubuntu

If you have the following Ubuntu error, I might have a fix for it.

fsck from util-linux 2.26.2
/dev/sda1 contains a file system with errors, check forced.
/dev/sda1: Inodes that were part of a corrupted orphan linked list found.

/dev/sda1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)
fsck exited with status code 4
The root filesystem on /dev/sda1 requires a manual fsck

Busybox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs) _

And believe me help command does nothing.

Solution:

Just fire a simple command to execute fsck manually.

fsck /dev/sda1

If some other filesystem is causing the error then mention that name after fsck.

It will show some processing. If it asks any questions like Fix(y/n)? always enter y.

In the end when (initramfs) reappears enter:

reboot

Well, that's all! It worked for me. Hope it works for you.

Create drop-down menu with image icons in Android

Hello devs! In this tutorial, we will be creating a drop-down menu on clicking a button in Android studio. Here is an image of how our menu is going to look: On clicking the hamburger icon, a vertical menu will appear with image icons of your choice. Above image is just to get an idea of what we are going to develop. Let's get started. Step 1: Open the layout file where you want the menu. Add the hamburger icon on an image button. <ImageButton android :layout_width= "50dp" android :layout_height= "50dp" android :src= "@drawable/ham" android :id= "@+id/ham" android :background= "#00000000" /> Note : #00000000 specifies 'transparent' background. Step 2: Add a vertical linear layout for the menu. Inside that, add nested linear layouts for horizontal rows. <LinearLayout android :layout_width= "wrap_content" android :layout_height= "wrap_content&quo

Convert List of user-defined datatype to String and back into List Java

There are times when it is necessary to convert a list of user-defined objects to string and later on retrieve it as a list in its original form. Example: like storing it into a Redis cache . How do we do that? ObjectMapper Steps: 1. ObjectMapper objectMapper = new ObjectMapper(); First, initialize ObjectMapper. 2. List<YourClass> listObj ; Create and initialize your list of user-defined object. where, YourClass is a class having multiple variables. Example - class YourClass{ String abc; String xyz; } 3. String convertedStr = objectMapper.writeValueAsString(listObj); This is the string conversion of the list. 4. listObj = objectMapper.readValue(convertedStr, new TypeReference<List<YourClass>>(); And we are back with your list object.
