I am having trouble installing the zotero plugin for LibreOffice on opensuse.

So far:
I have done a fresh install of zotero into /usr/local/bin/zotero
I have tried both automatic and manual installation
- I am not sure if the directories that zotero guesses for the LBO installation are correct
- Zotero gives this error message:

[JavaScript Error: "Unix error 2 during operation open on file /home/isaac/.zotero/zotero/u2sn0egh.default/session.json (No such file or directory)"]

[JavaScript Error: "uncaught exception: unopkg at /usr/bin/unopkg failed to install"]

[JavaScript Error: "uncaught exception: unopkg at /usr/bin/unopkg failed to install"]

version => 6.0.26, platform => Linux x86_64, oscpu => Linux x86_64, locale => en-US, appName => Zotero, appVersion => 6.0.26, extensions => Zotero LibreOffice Integration (6.0.4.SA.6.0.26, extension)

I have tried a manual installation.
- Libreoffice gives this error message when I click on the .oxt file

/home/isaac/.config/libreoffice/4/user/uno_packages/cache/uno_packages/lu36383g68.tmp_/Zotero_OpenOffice_Integration.oxt does not exist.

I am not sure what to do here.

I am on the latest versions of LibreOffice and Zotero
