You can probably install it via package manager that installs it via curl. If you want

What package manager installs things via curl|sh?

But why would I need a package manager?

I tend to compile everything from source on Linux. I don't want to be tied down to any distribution. So from my point of view I'd agree - I understand why curl/sh is used, it is super convenient, I also use it for installing Rust. But I also dislike it. (Naturally for Rust I need rust for the bootstrapping, so I understand that solution. But I still dislike it too.)
