Weird errors when installing lazyvim in docker

[Bloodsnake]

Hello, I tried installing neovim and lazyvim inside a docker container. Here is the Dockerfile I wrote for this:

FROM debian:latest

# init apt
RUN apt update -y && apt upgrade -y && apt autoremove -y

# install base packages and nivm dependencies
RUN apt install -y \
    git \
    iputils-ping \
    curl \
    unzip \
    fish \
    # nvim
    ninja-build \
    gettext \
    cmake
    
# build and install neovim
RUN cd /tmp && git clone https://github.com/neovim/neovim && \
    cd neovim && \
    git checkout stable && \
    make CMAKE_BUILD_TYPE=Release && \
    make install && \
    cd .. && \
    rm -rf neovim && \
    apt remove ninja-build -y

# layzvim
RUN git clone https://github.com/LazyVim/starter ~/.config/nvim && \
    rm -rf ~/.config/nvim/.git && \
    nvim --headless +LazyHealth +q

# Avoid container exit.
CMD ["tail", "-f", "/dev/null"]

After building the image and running the container I go into the container by executing: docker exec -it dev-container /bin/fish
When I first run nvim and the plugins are supposed to get installed I get these errors after some seconds:


I am able to to ping github.com inside the container.

No error in my container. Seems like your network router issue.
