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.

donko3005: Should be fixed after upgrading gns3-server.

smart2128: I don't know. I would keep the old package around to be able to downgrade just in case.

@buzo 3.1.0a2 is in the alpha stage. Do you think it is safe enough to replace 3.0.6? Thank you in advance.

After upgrading to the latest version it shows me this error while launching gns3. It looks like its missing a python dependency

@smart2128 thanks I downgraded to 0.52.1-1 and it works now

@donko3005 as a workaround, you can try downgrading python-starlette.

The build fails from my side

==> Starting build()...
/home/USER/.local/share/mise/installs/python/3.14.2/bin/python: No module named build
==> 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.

RocketDev commented on 2026-01-11 11:19 (UTC)

Since recently python in Arch upgraded to 3.14, please increase pkgrel to help users update their package to python3.14 automatically.
