I unintentionally removed Julia kernel from Jupyter note book. after that I tried the code `] build IJulia` to get that kernel back to Jupyter but it did not worked out and the Julia kernel folder is not created after several attempts.  
Any help is appreciate, by the way I am new to Julia and my operating system is ubuntu20

I don’t know if this would work, but you could try to delete the `~/.julia/compiled/IJulia/` folder, then rebuild before trying `using IJulia`. Make sure you’ve closed any open instances of Julia first.
