==> ERROR: A failure occurred in build().
Aborting...
-> error making: gns3-gui-exit status 4
-> Failed to install the following packages. Manual intervention is required:
gns3-gui - exit status 4
what can i do to successfully install gns3-gui??
Now it compiles and runs fine - no hustle needed.
Version 3.0.6 has landed whit init Qt6 and Python 3.14 support.
Since recently python in Arch upgraded to 3.14, please increase pkgrel to help users update their package to python3.14 automatically.
AUR package python-pyqt5-extra-modules enables the modules that were removed from python-pyqt5 that affect some AUR packages such as gns3. Full disclosure that I did personally make the package. Was primarily motivated to get gns3 working :)
I have found success installing GNS3 using pyenv to create a dedicated Python 3.12.8 environment using pyenv install 3.12.8 and pyenv shell 3.12.8 to set up the shell.This prevents dependency conflicts and avoids breaking core system packages. These are all the dependencies you need to install to run gns3 command when u are in the env shell
pip install setuptools distro jsonschema sentry-sdk truststore aiofiles aiohttp aiohttp-cors async-timeout Jinja2 platformdirs py-cpuinfo psutil PyQt5 sip
and you can alias gns3='pyenv shell 3.12.8 && gns3' for quick command without having to write everything out
(if there is anything wrong please point out as im a beginner and this was written with the help of ai but i have found success this way without breaking system packages or workaround)
@smart2128 pipx worked. I appreciate it.
To everybody who is having problems running gns3,I suggest to downgrade python-pyqt5 to 5.15.11-2 until the issue is resolved or somebody uploads a pyqt5 patch to the missing modules. It worked for me
@Revs32 Have you already tried pipx installation? You can find all details on GNS3 Linux Install official documentation and add PyQtWebEngine on pipx inject.
Hello. I tried the python virtual env workaround for this and I still got Please install the PyQt5.QtWebSockets module. Is there really no fix available for this so far, without breaking the system?

Upstream has split development of the major versions 2 and 3. This package will keep tracking the latest version. If you prefer version 2, there is now a separate package gns3-gui-2.
