Uknown error

I been trying to run gui in kali but it says unknown error I cant find the first password when was first installed and I have created new user and nothing any suggestions

If you have installed from Kali you’re not using the Greenbone Community Edition (GCE) so i have moved the topic to the better fitting category.

I’m also closing this post as a duplicate of Not able to create admin account - gvm-start not running due to several errors in KALI LINUX, please review this topic carefully (e.g. the “create new user” topic is discussed there already).
