The first thing I would do is to check the ownership and permission
masks of the /dspace/solr directory and everything below it. The
Servlet container (Tomcat, typically) must be able to read and write
these directories. The simplest way to ensure that is for them to be
owned by the account which runs the container.

Hi ppl. I had the same problem.

I was running Dspace 6.3 into Ubuntu 18.11 with Tomcat 8. Las week I do-release-upgrade (18.11 -> 19.04). Then, because Ubuntu 19.04 don't use Tomcat 8, I need to install Tomcat 9. Everything works fine except Solr. The problems seems to be permissions, but I already changed and nothing happens. The error is always the same:

I tried adding dspace to tomcat group and tomcat to dspace.

I chown tomcat:tomcat to /dspace/solr

I assign -just to test- chmod 777 to solr.

Nothing different happend.

Thanks

Well I fix it this way:

Following this guide I install Tomcat9 under dspace user:

https://linuxize.com/post/how-to-install-tomcat-9-on-ubuntu-18-04/

I test this way because it seems to be a permission problem. I tried changing permissions and owner before but nothing changes. I don't know why. Anyway... It works now.
