SIGILL: Illegal operation
This is my first introduction to Nim so excuse me if I am doing something wrong.

My OS is Xubuntu 20.04.

I downloaded latest [pre-built binaries](https://nim-lang.org/install_unix.html), unpacked them and linked ./bin directory to /bin

I've tried to run helloworld. It compiles and runs just fine!

But when I trying to install something I get errors (no matter with sudo or not)

For example:

```fish
> nimble install nico
    Prompt: No local packages.json found, download it from internet? [y/N]
y
    Answer: Downloading Official package list
SIGILL: Illegal operation.
```

Also I tried to just run `install.sh` earlier but this script doesn't create nimble binaries at all. I have no idea why.

I don't want to install Nim from official repositories because it's super old there.

And I don't want to build it from source because it's not fun 😺
