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 signature issue you seems to have an own installation either build from source or installed via 3rdparty repositories. For such installation 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.
To solve your issue you might want to give the following topic below a try. Researching the reason and possible issues of the “unsafe permissions on homedir” might worth another try.
