Current thread 0x00007fa26edb1740 (most recent call first):

I tried installing it, and it’s running fine, how did you install it ? Since it’s in debian repository, all you have to do is “sudo apt install gns3”

Did you change things like your python path ?

You dont say which parrot you use but with parrot security i had the same problem.

There is 2 way to resolve it but i prefer the second one:

First solution: Edit the 3 python script located at /usr/bin/gns3 /usr/bin/gns3server /usr/bin/gns3vmnet and replace the first line by #!/usr/bin/python3

2nd solution:
make a backup of /usr/share/gns3/gns3-server/bin/python3 and /usr/share/gns3/gns3-gui/bin/python3 like that:

sudo mv /usr/share/gns3/gns3-server/bin/python3 /usr/share/gns3/gns3-server/bin/python3.bak
sudo mv /usr/share/gns3/gns3-gui/bin/python3 /usr/share/gns3/gns3-gui/bin/python3.bak

After create a symlink for python3 in the precedent folder like that:

sudo ln -s /usr/bin/python3 /usr/share/gns3/gns3-gui/bin/
sudo ln -s /usr/bin/python3 /usr/share/gns3/gns3-server/bin/

And after thats use the gui launcher of gns3 in the menu and all works fine :wink:

@no0b i think he make like me install by the official site

You can install gns3 using python-pip for latest version (deb package on the repo is out of date i think).
pip install gns3 or sudo pip install gns3
This is gns3 information from pip server

$ pip search gns3
gns3-gui (2.1.8)            - GNS3 graphical interface for the GNS3 server.
gns3-server (2.1.8)         - GNS3 server

Hi, I tried to install it with pip but it’s showing this error. Can you help? Is it about python 2, python 3 problem?

A little update: you must install gns3-server using pip as well. There must be other dependcies (i don’t really remember them all).
