        My mistake. I restarted the app too early.
        After the full download of almost 8 GB EN n-gram dataset, you need to give your Cloudron instance enough time to unpack and move the files to (by default) /app/data/ngram/en.

        In my case, it took more than 15 minutes to meet the requirements.
        The moment you restarted the app too early, the zip file was not unzipped completely. In this case the error occurs and you have to start again from the beginning.

        Search your logs for ===> en ngram dataset has been installed.

          did the n-gram download finish and is this also happening after an app restart?

            @nebulon yesterday I followed the documentation from here https://docs.cloudron.io/apps/languagetool/.
            By the way: Is there a hint if it is important to comment out NGRAM_DATASET_PATH? In my case I only commented out NGRAM_DATASET=("en").

            And yes: it is a permanent error. Every time I restarted the box, the same error occurred. Fun fact: the moment I comment NGRAM_DATASET=("en") again and restart the app, the error still occurs.

            Q: is there an option to "redownload"?

              @luckow NGRAM_DATASET_PATH has a default set to /app/data/ngram so that does not need to be set, it is only there if someone want to move that to a volume due to the required disk size.

              Currently you have to delete the folder for that specific language to trigger a redownload after app restart.

                  The latest package version does not require the manual restart anymore, but will restart the internal component automatically after the download has finished.
