When I try to run an existing or new report I get S1000 error from MYSql.An exception of type com.sun.star.uno.RuntimeException was caught.
Worked in Libreoffice 5. Current Libreoffice is 6.0.3.1, Build id 00m0 Build # 2.
Maybe the same as https://forums.opensuse.org/showthread.php/530873-Languagetool-4-1-Error-while-adding-it-with-Extension-Manager-in-LibreOffice-6?p=2865712#post2865712 .
Although, that already was a problem with 5.x (from the 42.3 Update repo).
Still, I would suggest trying to install the packages from the LibreOffice:6.0 repo.
Thanks. The steps in the link fixed it up.
