[Pkg-mailman-hackers] Bug#922243: mailman3-full : Depends: mailman3 but it is not going to be installed

[K E N O]

Hi,

Thanks for your help! :) I thought so, too, but I still doesn’t work. In detail, I changed my `/etc/apt/sources.list` to:

> ## Note, this file is written by cloud-init on first boot of an instance
> ## modifications made here will not survive a re-bundle.
> ## if you wish to make changes you can:

Then I tried to execute `sudo apt update` and `sudo apt install mailman3-full`; the result is the same:
