I earlier was having an issue. I had solved that also. But, I am facing it again. Same issue. Same error. It's been three times I have faced the issue. I had solved the issue same way every time. But, if it always happens than it totally irritating.
If that happens that too often, it may mean that your hard drive is faulty. You can check your hard drive status through S.M.A.R.T. data with
gnome-disks ("three dots menu"/"hamburger" menu) and watch for any errors count or anything related to sectors.
Faulty RAM may also cause such issues, as well as damaged solders (CPU, chipset, motherboard, etc) if your PC stayed too hot (e.g CPU over 70C, etc) for long enough.
