With some difficulty I could install LanguageTool 5.2 fromhttps://extensions.libreoffice.org/en/extensions/show/languagetool In LibreOffice 126.96.36.199. I work in Ubuntu 20.04
sudo apt-get install libreoffice-java-common which seems to be required.
Language tool seems to be installed Ok if I go to LibreOffice menu → Tools → Extension manager
But when I try to check my text I get the error message: “LinguisticServices failed! LanguageTool can not be started!” And LibreOffice hangs after that. I have to force to quit.
What happened and how can this be solved?
