You will be a taken to this page https://julialang.org/downloads/, if you scroll down you will see something like this:

I clicked on the 64-bit thing for Generic Linux x86. Once you do that a file named julia-1.5.2-linux-x86_64.tar.gz will be downloaded. Extract it to your home directory and open ~/.bashrc and add it this at the last:

# Add Julia to PATH
export PATH="$PATH:$HOME/julia-1.5.2/bin"

this tells your computer to look into ~/julia-1.5.2/bin when you call julia. Just for once type this in terminal:

$ source ~/.bashrc
