NextCloud ========= NextCloud is a fork of OwnCloud, which seems to be more supported by the community. For an easy installation and maintenance, I use snap. Due to my dynamic DNS service, Lets Encrypt will not provide an SSL certificate. So fallback is self-signed. .. code:: sh sudo snap install nextcloud sudo snap run nextcloud.enable-https self-signed You have to wait a few minutes, but without further ado, it works. Of course, your browser will complain about the self-signed certificate being unsafe, but you ignore that. Follow the website's instructions for further configuration. Out of the box, NextCloud comes as a Dropbox clone. Activating features like addressbook and calendar requires more configuration as admin. .. warning:: Disabled NextCloud. Must use IP internally and DynDNS externally, because my router cannot fix the intern DNS.
