G_path_get_dirname: assertion 'file_name != NULL' failed

Hi, when choosing the category for a topic please try to have a look at the category description for each category first:

The current used category is/was Greenbone Professional Edition - Greenbone Community Forum (Description: About the Greenbone Professional Edition category - Greenbone Professional Edition - Greenbone Community Forum) which is about the downloadable ready-to use virtual machine.

Based on your posted issue it sees you have an own installation either build from source or installed via 3rdparty repositories. For such installations the https://community.greenbone.net/c/gse (Description: About the Greenbone Community Edition category - Greenbone Community Edition - Greenbone Community Forum) needs to be chosen.

I have moved the topic to the correct category for now. It could be possible that the info above is made more prominent / easier to find in the future.

Comparing this versions with the latest ones of GVM-9 (end-of-life, initial release 2017-03-07) - Greenbone Community Edition - Greenbone Community Forum those are quite outdated.

Please update to the recent releases and try again.
