Permission denied when installing MapDB persistence

Setup, Configuration and Use Beginners

When I try to install MapDB via PaperUI, I get the following error message:

[ERROR] [st.core.extensions.ExtensionResource] - Exception while installing extension: java.io.IOException: Permission denied

I have also installed JDBC MariaDB persistence, this works well and as expected.
MapDB however doesn’t store any values - I guess since it is not installed properly.

I use the latest offline snapshot, all relevant folders are owned by openhab. Do you have any suggestions on how to deal with this error?

apt-get purge openhab2-offline
apt-get install openhab2-offline

And the installation works without problems. Should do this on a daily basis :slight_smile:
