Nvm fails to install on bitbucket pipelines sometimes

[vivere-dally]

Operating system and version:

see docker image

How did you install nvm?

    export NVM_DIR="$PWD/nvmhome"
    mkdir "${NVM_DIR}"
    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

    echo "export NVM_DIR=\"${NVM_DIR}\"" >> ~/.bashrc
    echo '[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm' >> ~/.bashrc

    source ~/.bashrc

    nvm install 20.12.2

In my pipeline the nvm install command is flaky. Any lead to make it more stable? It fails quite often

Then the install from source fails as well with the same curl error

Same thing happens for us on bitbucket pipeline:

If it were just the first problem, I’d say it’s nodejs.org - but if bitbucket is unable to connect to GitHub also, that suggests an issue with bitbucket. Have you filed an issue with them?
