Could not send Dynamips command 'vm set_ghost_status "R1" 2' to localhost:34923: Connection lost, process running: False error in gns3

I'm trying to run c7200 router image in gns3 on debian distro. But it's throwing me above error. I saw a similar issue reported for fedora. But couldn't see the solution to it.

Sounds like your c7200 image is unstable and/or Dynamips has crashed as a result. What is your IOS image name?

Hey bro. I'm running Cisco 7200 124-24.T5 on my debian machine. Could there be any problem with gns3 in supporting IOU images? In Ubuntu based distro, we use following commands for IOU support:

sudo dpkg --add-architecture i386
sudo apt update
sudo apt install gns3-iou

Do we have any such commands to enable IOU support in debian? Also, I want to understand what these commands do that you're able to run IOU images in Ubuntu distro?

How have you installed Dynamips?

Also, the above commands are only for IOU. Then basically enable the i386 architecture and gns3-iou package basically installs the correct libssl and configure the required symbolic links.

[Durgesh002]

Yes I have installed it. But, I've moved to Linux Mint since my Debian broke.

[grossmj]

Do you have the same problem on Linux Mint?

[Durgesh002]

No. For linux mint, it works perfectly fine. I'm able to run the same image without any issues.

[grossmj]

Have you installed Dynamips via apt or did you compile it?

[Durgesh002]

I've used following commands for different distros.
For Linux mint:

sudo add-apt-repository ppa:gns3/ppa
sudo apt update
sudo apt install gns3-gui gns3-server
sudo dpkg --add-architecture i386
sudo apt update
sudo apt install gns3-iou

With these commands, GNS3 is working fine.

For Debian:

sudo apt update
sudo apt install python3 python3-pip pipx python3-pyqt5 python3-pyqt5.qtwebsockets python3-pyqt5.qtsvg qemu-kvm qemu-utils libvirt-clients libvirt-daemon-system virtinst dynamips software-properties-common ca-certificates curl gnupg2
pipx install gns3-server
pipx install gns3-gui
pipx inject gns3-gui gns3-server PyQt5

With this, GNS3 wasn't working how i wanted it to be.
