The problem is much broader than that as Rob also points out.
Here just a few, but important shortcomings:
1.) You recommend Docker as preferred deployment option - this information is not available in the manual. I personally did not know that, despite the fact that I work a lot with Seafile.
2.) The Docker install instructions don’t mention Seafile Server 8 (as pointed out by Rob).
3.) The install script page …
a.) does not detail the installation on current OS (i.e., Debian 10, Ubuntu 20.04)
b.) does not work for Ubuntu 20.04 (I was told by a customer, did not test myself)
c.) does not elaborate on Seafile 8
4.) The manual installation makes no mention of Ubuntu 20.04. It also contains some flaws.
5.) The SQLite option is described as suitable for Home/Personal Environment. Why should I as a home user opt to use SQLite if
a.) my RasPi has 4 cores,
b.) the support in the forum is inferior to the MariaDB/MySQL option because it’s rarely used and
c.) even the developers say that they don’t devote attention to it.
This are just comments on the basic installation. I have not gone into special topics.
I have created a pull request for the manual installation instructions close to a month ago. Once it has been merged, I am happy to continue to work on the page.
The manual instructions are crucial as they serve as a reference.
