Seafile installation issue on Raspberry PI, aarch64

I tried install a seafile 6.0.7 on the raspberry PI3 with the Arch operating system. Architecture is aarch64. Also I installed all prerequisities than python2.7, python-mysql etc. But I over and over failed.

This is output from setup-seafile-mysql.sh:

Traceback (most recent call last):
File “setup-seafile-mysql.py”, line 1461, in
main()
File “setup-seafile-mysql.py”, line 1414, in main

File “/usr/lib/python2.7/subprocess.py”, line 1024, in _execute_child

OSError: [Errno 8] Exec format error

Can you help me please

Someone got it working with Aarch64, maybe that helps: Seafile server on arm64 (aarch64). - WORKING
