[Mailman-Users] Mailman 3 The Definitive Mailman Suite - Download error

[Henrik Rasmussen]

Is this list the correct place for Mailman 3 questions?

I was in the progress of installing the Mailman3-bundler as it got obsolete. As a consequence the old Mailman-bundler documentation was changed to refer to http://docs.mailman3.org/en/latest/devsetup.html "The Definitive Mailman Suite Development Setup Guide". I am now starting over.

Both in the Mailman Suite Setup Guide section "Set up and run Mailman Core" http://docs.mailman3.org/en/latest/devsetup.html#set-up-and-run-mailman-core , and the Mailman Core doc at http://mailman.readthedocs.io/en/release-3.0/src/mailman/docs/WebUIin5.html#gnu-mailman-3 the code is supposed to be downloaded using the command "git clone git at gitlab.com:mailman/mailman.git", but I get a Permission Denied

  (venv-3.5) [mailman at lstapp01pl ~]$ git clone git at gitlab.com:mailman/mailman.git

How should I download the Mailman core?
