I am trying to install on a Raspberry PI 4
Hi,
I am trying to install Open Semantic Search on a Raspberry PI 4, the model with 8GB of RAM and a quad core ARM processor.
I have tried a few times, I have just done another complete wipe and reinstall with the latest Raspbian Buster image, I then ran updates.
Then i followed the website guide, https://opensemanticsearch.org/doc/admin/install/search_server
Downloaded the latest, https://opensemanticsearch.org/download/open-semantic-search_20.01.17.deb
and followed instructions.
I then got some errors at the end of the process, so i rebooted.
I now get this error message when i try and run, sudo apt-get updates then sudo apt-get upgrade,
Setting up open-semantic-search (20.01.17) ... openjdk version "11.0.8" 2020-07-14 OpenJDK Runtime Environment (build 11.0.8+10-post-Raspbian-1deb10u1) OpenJDK Server VM (build 11.0.8+10-post-Raspbian-1deb10u1, mixed mode)

Could anyone suggest any further steps ?
There is another error message when i re-run,
sudo dpkg --install open-semantic-search_20.01.17.deb

Previously i have tried installing Solr, but it seems to need extensive config to integrate and so did not help.
The debs are for x86 architecture and the Pi has an ARM processor. So you would have to literally clone repos and build it all from scratch. That is doable, but it is a LOT of work.
OSS is pretty demanding, I gave it a virtual machine with eight cores and sixteen gig. What is the motivation for trying to put it on such a small device? You'd likely do better with an old, inexpensive laptop if you're wanting some sort of home appliance.
