Ubuntu 20.04 afterdowngrading to Libreoffice 6.4, javaloader error

kdb_research
I removed LBO 7 completely, and reinstalled the default version from the Ubuntu repos (working nicely with Zotero on another machine).

I now get the error that people were previously getting from OpenSuse versions of LBO:

(com.sun.star.uno.RuntimeException) { { Message = "javaloader error - could not find class com/sun/star/comp/loader/JavaLoader", Context = (com.sun.star.uno.XInterface) @0 } }

java -version, returns

openjdk version "11.0.11" 2021-04-20
OpenJDK Runtime Environment (build 11.0.11+9-Ubuntu-0ubuntu2.20.04)
OpenJDK 64-Bit Server VM (build 11.0.11+9-Ubuntu-0ubuntu2.20.04, mixed mode, sharing)

libreoffice-java-common is installed.

I realise that this is a Libreoffice problem.

    You need to select a JRE in LibreOffice. See https://www.zotero.org/support/word_processor_plugin_troubleshooting#installation_error

    I did have a JRE installed in LBO (or it thought it was installed), but it wasn't working -- despite trying three different versions of LBO and three openjdk versions.

    I managed to fix this by completely removing LBO, and then using Synaptic to search for remnant packages, including the uno-libs, and the liblibreoffice-java -- my guess is one of those was messing with the JRE.

    Reinstalling LBO 7.1 from the ppa then worked. Zotero is back and running properly. Yay.
