Ubuntu – Ubuntu asks me to do fsck on every boot

bootfsckgrub2

I recently installed Ubuntu and on every boot I see this

    /dev/sda2: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
        (i.e., without -a or -p options)
fsck exited with status code 4
The root filesystem on /dev/sda2 requires a manual fsck

Afer running manual fsck ubuntu boots normally clean.

However, after boot, I see the lock icon on all folders in my system and none of apps run. I also started seeing issues with my browser

Firefox is already running, but is not responding

Not sure what's wrong here. I have been running fsck manually and booting. Any pointers or help here.

Edit :
Tried executing as below per suggestion of @byte-commander in comments

sudo smartctl -a /dev/sda –> https://pastebin.com/uMng5VZf

Since I was doing fsck /dev/sda2

sudo smartctl -a /dev/sda2 –> https://pastebin.com/89r50aNQ

Best Answer

type fsck /dev/sda2 and press enter whenever the terminal asks for input.

Now after the process finishes, type: reboot

After rebooting, open the terminal. Make sure you have internet connectivity and type:
sudo apt-get clean
sudo apt-get update
sudo apt-get updrade

Now, your system will start normally from now on.
