Create Real Time Backup Server tutorial Debian 10.4 seafile-pro-server_7.1.5_x86-64_Ubuntu

Seafile Server
1

At the moment I try to set up two VM based on Debian 10.4 headless minimal installation.

One virtual machine is called seafile-master the other one seafile-slave.

Seafile will be hosted by gunicorn, no intermediate reverse proxy etc. for the sake of creating a tutorial.

I downloaded seafile-pro-server_7.1.5_x86-64_Ubuntu.tar.gz from https://customer.seafile.com/downloads/

Using mariadb on both vm with replication (that part works like a charm). There is one mariadb on each vm (localhost root access only).

But there are several problems:

  • ImportError: cannot import name ‘CaptchaField’ from ‘captcha.fields’ (No matter how I install captcha, apt or pip3 or by pip3 into a venv)

  • When Seafile replication runs, seaf-backup-cmd.sh status tells me that nothing is synchronized at all (zero) but mariadb replication works (even after several hours no Seafile sync).

  • Countless python issues (package versions are sometimes mutual exclusive, pillow for an example), even permission issues with the seafile user that runs seahub.sh as a systemd service when installed like tutorials show.

Problem 1: I miss the list of apt-get packages and pip3 packages that are needed to make it run.

Expected: A working set of commands for apt-get and pip3

Hint: Official documentation failed: https://download.seafile.com/published/seafile-manual/upgrade/upgrade_notes_for_7.1.x.md

Further problems will be discussed later.

Thanks for participating!

->pip3 list | grep -i cap
django-simple-captcha 0.5.6

=> Try pip3 install django-simple-captcha

Thanks germeier for your quick reply, here is the outcome

pip3 install django-simple-captcha

Requirement already satisfied: django-simple-captcha in /usr/local/lib/python3.7/dist-packages (0.5.12)
Requirement already satisfied: Pillow!=5.1.0,>=2.2.2 in /usr/local/lib/python3.7/dist-packages (from django-simple-captcha) (7.2.0)
Requirement already satisfied: django-ranged-response==0.2.0 in /usr/local/lib/python3.7/dist-packages (from django-simple-captcha) (0.2.0)
Requirement already satisfied: six>=1.2.0 in /usr/lib/python3/dist-packages (from django-simple-captcha) (1.12.0)
Requirement already satisfied: Django>=1.8 in /usr/local/lib/python3.7/dist-packages (from django-simple-captcha) (3.0.8)
Requirement already satisfied: asgiref~=3.2 in /usr/local/lib/python3.7/dist-packages (from Django>=1.8->django-simple-captcha) (3.2.10)
Requirement already satisfied: pytz in /usr/local/lib/python3.7/dist-packages (from Django>=1.8->django-simple-captcha) (2020.1)
Requirement already satisfied: sqlparse>=0.2.2 in /usr/local/lib/python3.7/dist-packages (from Django>=1.8->django-simple-captcha) (0.3.1)

On my Ubuntu 20.04 Server running Seafile 7.1.5 there is also installed:

->dpkg --list | grep -i captcha
ii  python3-django-captcha                0.5.6-2                             all          Django Simple Captcha Django application

At the moment I have no further idea what might be missing on your system.

My output is:
ii python3-django-captcha 0.5.6-1

Here is the list of packages on the system (resulted from last installation try)
I hope it will not scare off readers :slight_smile:

Anybody knows a good and working tutorial that creates Real Time Backup Server from scratch in one of the following scenarios using Ubuntu20.4 LTS or better Debian10.4?

  • Pro -> Pro

(The Arrow stands for “Real Time Backup synchronization”)
