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-server-2.

3.1.0a3 will fail to start with

2026-06-22 17:13:33 CRITICAL gns3server.server:327 Critical error while running the server: No module named 'mcp'

if python-mcp is not installed. It should be added as a dependency.

gns3-server require telnetlib3 when starting but had a dependency issue not finding a pacman or AUR package to fulfill this need. (Pyhton 3.14.4)

I created this package to fix the issue: https://aur.archlinux.org/packages/python-telnetlib3. Consider adding this as a dependency.

Feel free to email me if you need.

Best regards.

For gns3-server 3.0.6, need version of starlette < 1.0.0 in depends, in PKGBUILD:

depends=(
...
    python-zstandard
    uvicorn
    'python-starlette<1.0.0'
)

Zorbatron commented on 2026-03-31 14:23 (UTC)

Upstream has fixed the issue with https://github.com/GNS3/gns3-server/pull/2652.

@alnnuu unfortunately until upstream updates you'll have to downgrade python-starlette to 0.52.1-1 (the last release before 1.0.0-1).

I get the following error when trying to launch gns3server directly:
