Early access to new WebUi - GNS3 2.2.0 alpha 4 upgrade on Linux

GNS3 version 2.2.0 alpha 4 has been released, it gives you early access to the new web-ui with the upgrade of v2.2!

Major new features are the WebUi (read only for now), a new GNS3 VM based on Ubuntu 18.04 LTS, Hyper-V support for the GNS3 VM, new symbols (affinity theme), new template creation system, link status detection for Qemu VMs, custom adapters configuration, console support for clouds, new project import/export and much more! 

Please see What’s new in GNS3 version 2.2 for a detailed overview.

IMPORTANT NOTE to upgrade from 2.1.x and earlier versions of GNS3

Please do not upgrade if you are working on something important like a certification or something else. Understand there is no rollback possible once you open an older project in version 2.2

Backup all your projects, settings and snapshot the GNS3 VM. Version 2.2 is in alpha stage which means many things could be broken or not work as expected. Only advanced users who are comfortable with GNS3 should try this alpha release.

Linux installation

Ubuntu/Debian, install from our PPA:

sudo add-apt-repository ppa:gns3/unstable
sudo apt-get update
sudo apt-get install gns3-gui

For upgrading from the stable repository:

sudo add-apt-repository --remove ppa:gns3/ppa
sudo add-apt-repository ppa:gns3/unstable
sudo apt-get update
sudo apt-get upgrade

For upgrading from the unstable repository:

sudo apt-get update
sudo apt-get upgrade

For other Linux distributions, we recommend an installation via Pypi:

pip3 install gns3-gui==2.2.0a4
pip3 install gns3-server==2.2.0a4

This is the news I've been waiting for! For many of us this should make it easier to sneak in some lab time by just spooling up your server and then log into GNS3 via browser to lab! 

A final release is expected during the first half of 2019 and I am so excited!
