They installed a new virgin Debian server, with my public ssh key in root's
authorized_keys. I sign in as root via ssh and then it is routine::

  # apt install sudo
  # adduser luc
  # adduser luc sudo
  # adduser luc www-data
  # cp -a .ssh /home/luc/
  # chown -R luc:luc /home/luc/.ssh/
  # sudo apt-get install -y python3-pip

And then followed the instructions for :ref:`getlino.install.prod`.


command 'x86_64-linux-gnu-gcc' failed with exit status 1

The problem disappeared after doing::

  $ sudo apt install build-essential
  $ sudo chown -R root:www-data .

But maybe only the second command was enough.

Note that build-essential was installed automatically on the new :ref:`lf`
server::

  $ sudo apt list build-essential
  Listing... Done
  build-essential/stable,now 12.6 amd64 [installed,automatic]

I also opened (and did) :ticket:`3195` (getlino should install a bash_aliases).

And then released getlino 19.9.6, immediately followed by a bug-fix release
19.9.7

Note : I saw the following when running :cmd:`sudo pip3 install -U getlino`::

Maybe this is when I forget to specify ``sudo -H``.

Releasing Lino Avanti
=====================

I prepared the PyPI release for :ref:`avanti`.  :ref:`avanti.changes.2019`

I created :ticket:`3197` because I had the following error message when trying
to :cmd:`inv sdist release`:

  HTTPError: 403 Client Error: The credential associated with user 'luc.saffre'
  isn't allowed to upload to project 'lino-avanti'.
