Looking for some information as to why I cannot install Gns3. I’ve searched around the forum however I’m a bit perplexed how it seems that my issue is rather unique.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
gns3 : Depends: python-qt4 (>= 4.5) but it is not installable
E: Unable to correct problems, you have held broken packages.
+ **Logs/Terminal output** *(use pastebin or similar services)***:**
The GNS3 in the repo is old and apparently no longer supported. The proper way to install the latest GNS3 on Linux is documented on the GNS3 website.
For Debian Buster Refresh your metadata, and install the following packages:
sudo apt update
sudo apt install -y python3-pip python3-pyqt5 python3-pyqt5.qtsvg python3-pyqt5.qtwebsockets qemu qemu-kvm qemu-utils libvirt-clients libvirt-daemon-system virtinst wireshark xtightvncviewer apt-transport-https ca-certificates curl gnupg2 software-properties-common
Then install GNS3 from Pypi:
pip3 install gns3-server
pip3 install gns3-gui
And launch from terminal (or create icon) by running
PS: You will also need to install ubridge, which is no longer in the Parrot repository.
sudo nano /etc/apt/sources.list
Add the following repositories to sources.list:
deb http://ppa.launchpad.net/gns3/ppa/ubuntu bionic main
deb-src http://ppa.launchpad.net/gns3/ppa/ubuntu bionic main
Add the GPG key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F88F6D313016330404F710FC9A2FD067A2E3EF7B
sudo apt-get update
sudo apt install dynamips ubridge
Go back to sources.list and uncomment the 2 added repositories.
Let me try debian packaging for this gns3. totally forgot about it
Everything seems good. I’ll do actual packaging for it. And then try with the GNS3-server
gns3-gui, gns3-server, ubridge is almost ready. Basic debian packaging is completed. I just need to complete the whole debian standard which is pain in the arse and wait them to be on the repository.
dynamips is on repository but outdated and i’ll update it as well
