How to download https://github.com/MCMrARM/mcpelauncher-linux? [closed]

I can't download it because it gives me a 404 error. Also, it will say that I need libprotobuf17 but it isn't installable. Also, I'm using KDE Neon and 64 bit.

Any time I do

sudo add-apt-repository 'deb bionic main'

it will say Error 404 and give me some weird IP address. This is what i get:

I'm not sure how you've tried to download it, but since it's a Git repository, I suggest downloading it by using the git command to clone the repository. To do this, first install git if it's not installed:

sudo apt update
sudo apt install git

Then cd to whatever directory you want to download it to, and run:

git clone 

Assuming that succeeds (as it did when I tested it), the downloaded repository consists of the newly created mcpelauncher-linux directory and its contents.

With that said, if you want to download it in your web browser as a ZIP archive, you can do that. Click the "Clone or download" button and then click the "Download ZIP" link. For this particular repository, that's .

If these techniques don't work, there might be a problem with your Internet connection (or with your proxy configuration, if you browse the web through a proxy server), or perhaps a transient problem on GitHub (if trying exactly what you did before works now).
