Can you please help, getting below error installing gns3 2.1.10, running Debian with kernel 4.18, have munuallyinstalled python 3.5, not sure what is the problem.

Setting up gns3-server (2.1.10~xenial1) ... cp: cannot stat '/usr/bin/python3.5': No such file or directory cp: cannot stat '/usr/bin/python3.5': No such file or directory WARNING: Some error occured while updating /usr/share/gns3/gns3-server/bin/python3 Setting up gns3-gui (2.1.10~xenial1) ... cp: cannot stat '/usr/bin/python3.5': No such file or directory cp: cannot stat '/usr/bin/python3.5': No such file or directory WARNING: Some error occured while updating /usr/share/gns3/gns3-gui/bin/python3 Processing triggers for libc-bin (2.27-6) ...

Thanks in-advance.

  • As the error states that python3.5 is not in the path `usr/bin/python3.5` and you've built Python from source then your python3.5 path could be `/usr/local/bin/python3.5`. – Paandittya Sep 28 '18 at 12:31
  • Thanks, moved python3.5 files from /usr/local/bin to usr/bin/, and it install's fine, getting this error message, when running from terminal. Traceback (most recent call last): File "/usr/bin/gns3", line 5, in from pkg_resources import load_entry_point ImportError: No module named 'pkg_resources' – M0rph3us Sep 30 '18 at 10:38
  • See if this question helps [No module named pkg_resources](https://stackoverflow.com/questions/7446187/no-module-named-pkg-resources). Also I think it would be a better idea to direct your gns installation to use Python 3.5 from `/usr/local/bin/` rather than moving the whole Python installation to some other path. I do not have much idea about what all could go wrong if you move your Python installation but I can certainly say that such a fix would definitely cause unwanted problems. – Paandittya Sep 30 '18 at 10:59

Resolved Error Installing GNS3 for Linux

Hello M0rph3us ... This might help you.

$ sudo apt update

$ sudo apt install dirmngr

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F88F6D313016330404F710FC9A2FD067A2E3EF7B

$ echo "deb http://ppa.launchpad.net/gns3/ppa/ubuntu xenial main" | sudo tee /etc/apt/sources.list.d/gns3.list

$ sudo apt update

$ sudo apt install gns3-gui

Now press y and then press Enter.

When you see the following dialog message, select "Ok" and press Enter.

If you want ordinary users to run GNS3, then select "Yes" and press Enter. Otherwise select "No" and press Enter.

Now select "Ok" and then press Enter.

If you want ordinary users to use Wireshark to capture network packets, select "Yes" and press Enter. This is not what you want on a production environment, but it’s hassle free setup for testing as you won’t have to run Wireshark as root each time.

On a production environment, just select "No" and press Enter.

GNS3 should be installed.

Now reboot your computer with the following command:

$ sudo reboot
