404 error and "no release file" error.

[Botspot]

I am running Raspberry Pi OS 64-bit, and have run these commands:

pi@raspberrypi:~ $ curl -s https://packagecloud.io/install/repositories/swift-arm/etcher/script.deb.sh | sudo bash
Detected operating system as debian/buster.
Checking for curl...

Checking for gpg...

Installing /etc/apt/sources.list.d/swift-arm_etcher.list...done.
Importing packagecloud gpg key... done.
Running apt-get update... done.

The repository is setup! You can now install packages.

The above output looks good to me. But below, when I run sudo apt update, issues appear:

sudo apt update

Any ideas?

There are no 64bit versions, only releases for 32bit armhf at the moment. https://packagecloud.io/swift-arm/etcher

Okay thank you. Surprisingly, it turns out your 64bit Ubuntu arm64 .deb file actually successfully installs on Raspberry Pi OS 64-bit.

So that's what I opted to use in my app store. Speaking of that, have you heard of my RPi app store called Pi-Apps? It has a lot of cool stuff in it which otherwise would be hard to find/install. And it currently has 13,000+ users.
