I've made some progress after experimenting with an unrelated matter.
My current seafile host is an Bananapi M1 ( which is an armhf processor ). So quite low capable hardware but it's suitable for the job.
I managed to get seadrive running from repository by updating to stretch and installing seadrive-daemon:i386 from http://deb.seadrive.org stretch main
( https://github.com/haiwen/seafile-user-manual/blob/master/en/desktop/install-on-linux.md )
I advise you to use aptitude to update to stretch and install the seadrive package since it will resolve problems quicker if you happen to be in a similar situation.
I'm a little bit over-joyed I finally get to finish this setup. Hope I can help someone in the future by leaving remarks.
