Hi there,
I used Ansible to perform a fresh installation of Dataverse 6.6 on Debian 12.10 in March 2025. That went fast and smooth. However, when I create a dataset, it does not show up in the UI. It appears that SolrR does not work properly, in view of the numerous errors on solr.log (Unable to create core [collection1] ...).
It took me some time to realize that maybe my installed version of solr, which is 9.4.1, is not the right one. Since the recommended one is 9.8.1 in the release notes, should I upgrade Solr and will it solve the above issue?
Interesting. I'm out of my depth here (@Don Sizemore help!) but assuming you followed https://github.com/gdcc/dataverse-ansible#quickstart you should get the latest version of Dataverse (6.6 as of this writing) and (I would think) the version of Solr mentioned in the guides for the version of Dataverse (Solr 9.8.0 according to the Dataverse 6.6 guides).
It's odd to me that you got an older version of Solr, version 9.4.1.
Also, I'm not sure where you're seeing 9.8.1 in the release notes. We did have PR #11340 for 9.8.1 but we decided that 9.8.0 was good enough and closed that PR without merging it.
Indeed, I simply followed the quickstart guide from github.
The default version of SolR was updated in defaults/main.yml as of May 19, after I had finished installing.
And yes, version 9.8.0 is recommended, not 9.8.1 (my mistake).
Hmm, do you think it's reproducible? If someone follows the quickstart, do you think they'll get Solr 9.4.1 (an old version) instead of 9.8.0 (the correct version)?
Probably not if one gets the last release of https://github.com/gdcc/dataverse-ansible
But certainly yes with the Commit b0841ee of Mars 21:
https://github.com/gdcc/dataverse-ansible/commit/b0841eecec76c963979e4efeb98e45555fa543b9
Ok, well, if you think there is something to fix, please feel free to open an issue.
Meanwhile, as you said, yes, you should use Solr 9.8.0 with Dataverse 6.6.
Indeed, after reinstalling Solr 9.8.0 while following carefully all required steps (e.g., core creation) and reindexing, my datasets became visible in the UI of Dataverse 6.6 for the very first time :+1:
Problem solved, thanks a lot! :folded_hands:
Great news! :tada:
