Error creating core using configset

[rhayzahr]

I volunteer for a non-profit and were trying to get archivespace running on our VPS. Our Linux server allows us to install all the requirements. Java is installed, Solr is installed, MySQL Connector is installed, MariaDB come pre-installed (may need to change to mysql instead but that shouldn't be the issue now). Focusing now on Solr, I originally installed the most recent version, which i then removed and installed the 8.10.0 version. All of the configset files are in their proper directory. However when I go to create the core I get the following error that says it already exists but when I open Solr in a browser I'm met with this error:

ERROR: Error CREATEing SolrCore 'archivesspace': Unable to create core [archivesspace] Caused by: solr.ICUCollationField

&

archivesspace: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not load conf for core archivesspace: Can't load schema /opt/solr/server/solr/archivesspace/conf/schema.xml: Plugin init failure for [schema.xml] fieldType "sort_icu": Error loading class 'solr.ICUCollationField'

I've read the tech docs front to back and back to front, and watched the corresponding youtube video on this same subject but end up with the same result. The youtube video shows the same process I get, however does not check the Solr page in the browser.

I moved solr-analysis-extras-8.10.0.jar which contains the class ICUCollationField to the server/libs directory and got another error, but regardless, errors.

Any idea what i'm doing wrong?
