Hi, looks like it failed to connect to MongoDB database, check the following:

• mongoDB is running service mongodb status
• check mongoDB listen to the port 27017 (default port) netstat -nat | grep LISTEN

service mongodb status

The only OS we tested on is Ubuntu 16.04 TLS and I highly recommend you to use it.

[DFIRKuiper]

dear Fahad, could you provide the installer log file Kuiper-install.log also the service file /etc/systemd/system/mongodb.service

also try change the owner of the mongodb folder sudo chown -R mongodb:mongodb /var/lib/mongodb/

Hi,

I had the same issue and reinstalling MongoDB fixed it.

error msg:

After fixing the isssue:

Here are the steps you can follow to reinstall MongoDB 4.2 assuming you are running on Ubuntu 18.04:

sudo apt purge mongodb-org*
sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 4B7C549A058F8B6B
echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb.list
sudo apt update
sudo apt install mongodb-org
sudo systemctl start mongodb
sudo systemctl enable mongodb

If you are running on Ubuntu 16.04 just replace the 5th line with:

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb.list

Good luck!
