Maltego not working

Whenever I am trying to work on Maltego CE it is not responding at all. When tried to open in terminal it is showing the following warnings. Please look at this issue:

I am also having a similar issue with maltego, not sure if it is the opnjava version that is installed. I have 13. I try running maltego and nothing happens.

Works fine for me both root user and normal user. Make sure you try different java jre or anything related.

it was working fine for me before too, but after some days it stopped working. I had also reinstalled the program and still its shows the same

even with diffrent java versions (8,11,13)

  1. Type Maltego in Menue search, 2) select ‘Maltego memory config’ 3) Set path to default-java
  2. Eventually decrease max. memory (had to do down from 32GB to lower value).

(probably the default settings were reactivated, for me worked with this memory config change, also removed/reinstalled Maltego which was probably not required at all ).

Thanks, bro this helped out :slightly_smiling_face: :smiling_face_with_three_hearts:. The main problem happening was solved with your help :innocent:, but after updating and upgrading ,maltego goes to 0kali-release than the downloaded version from web, disabling maltego_memory_config from further use


following it then after-screenshot (apt update && apt full-upgrade )
but maltego accessable

Thanks bro :slightly_smiling_face:

**SOLVED **
iam also having the same issue with maltego…

  1. go to the official website of maltego…

dont use apt upgrade…

2.install maltego .deb file using your terminal like sudo apt install ./Maltego.v4.2.18.13878.deb

3.type maltego_memory_config

its open a java options window, and please reduce your maximum memmory … i recommended 1350mb

ath replace your path to /usr/lib/jvm/default-java
and simply click ok

  1. lastly type maltego in your terminal

        **good luck and good bye**

I followed your instructions and loaded the newer version of Maltego. It worked perfectly.
As reported, when I upgraded my machine, It Downgraded my version of Maltego .

dpkg: warning: downgrading maltego from 4.2.19 to 4.2.17.13809-0kali1

This again did not work. I was using parrot-upgrade, to avoid troubles I have had with full-upgrade not having available servers.

My memory is a little foggy on this, but, Isn’t the full-upgrade the apt version that changes the Operating System back to the standard set by Parrot, and upgrade is the version of apt that keeps the changes made by the user?

If I use upgrade it comments that it is no longer used and changes it to full-upgrade, forcing the failure of the changes that I have made. Yet, this does not always happen. There are several changes that I have made that survive the full-upgrades.

What is going on?

Hi. Not to open a new thread, I have the same issue that Maltego is not opening for me.

When I run from the menu [clicking on icon], I get a right side notification that maltego is starting, get the administrator notification for password, I enter that and then nothing. Not even a splash screen.

I will post a terminal output. I assume there’s missing some java dependencies but want to make sure. Here is the terminal:

Update:

Using Synaptic package manager, I went into “Java programming language” section, installed every single version of jdk and jre there is, and now it’s working normally.

However, the package might need updating to a more recent version which is available from the website.

But just know that logging in as root is never preferred, (where you did sudo su)
For the same reason root account is disabled by default.
You have direct perms to burn your system with root, so better just use sudo (only sudo) for getting the perms for what you are doing, but not logging in as root and working there.

Much appreciated your advice, I’m very grateful! :+1::+1::+1::+1:

Hello I have another error when I launch maltego it asks me for the password (normal) but it does nothing yet I still have a notification that tells me who is launching and it’s the same for the terminal.
An answer to this problem? :thinking:

ah sorry :sweat_smile: I looked at your advice and it now works no more parrot with bugs! Thanks

worked with this instruction, thanks :grin:
