Curl: (23) client returned ERROR on write of 16375 bytes

I have a blank ubuntu 24.10 installation and I tried to follow the installation instructions:

curl --proto '=https' --tlsv1.2 -LsSf https://setup.atuin.sh | sh

leads to:

$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
info: downloading installer
warn: curl: (23) client returned ERROR on write of 951 bytes
error: command failed: downloader https://static.rust-lang.org/rustup/dist/x86_64-unknown-linux-gnu/rustup-init /tmp/tmp.L9OLO5lxzK/rustup-init x86_64-unknown-linux-gnu

did I forget something crucial?

I wonder how I can move this into “Help” topic. Can anyone help me?
