the request for seafile packages available in the official distribution repositories was already mentioned by many others.
I’d like to emphasize somethings different: the ability to customize/choose components during the installation : there are many ways of how to install seafile: sqlite, mysql, mariadb,… , external or internal DB, …, apache, nginx,… standalone or cluster,… ssl or not,… additional security stuff like fail2ban, ufw,… In my opinion there is not the one only way that is right for everybody.
So it would be really great, if there would be an official installation package that asks the user at least about the most important choices mentioned above, configures them accordingly and sets up all the other stuff, that already were implemented in the former installer scripts (e.g. startup scripts etc.)
Thanks and best regards,
