I have found the problem. Oh, just the same as you have just wrote Daniel.
It was the missing libreoffice-java-common package that is needed to install Language Tool with success. The problem was identified on: http://languagetool.org/issues/ with: " On Ubuntu, install the libreoffice-java-common or openoffice.org-java-common package. One problem solved by this is getting a long error message with "NoClassDefFoundError" during installation. See this blog posting for details. " the stacktrace on http://languagetool.org/images/class_not_found.png was the same. So, after installing libreoffice-java-common package all works fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1213130 Title: libreoffice writer extension manager failed on installing "Language Tool" extension with java exception To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1213130/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
