I've hacked my way around it for now.

Based on Change log, the thing that changed the most is supported Python version. It dropped Python 3.4, the lowest version is Python 3.5.3. As my Arch has Python 3.7, and GNS3 also supports Python 3.7... I've changed the package requirements for the given package.


After that I had to do pip install aiohttp-cors==0.5.3

I MUST SAY THAT I DON'T RECOMMEND DOING THIS!! It is really, really ugly workaround.

Well, that didn't work for me, unfortunately. As it needs version even lower then v.3.0.0.

pip freeze: async-timeout==3.0.0

gns3server: pkg_resources.DistributionNotFound: The 'async-timeout<3.0.0' distribution was not found and is required by gns3-server

I'm not able to downgrade to version python-async-timeout-gns3-2.0.1-1 as it breaks another package.

I have downgraded python-async-timeout-gns3 to version 3.0.0 to fix this.

The latest update is not working for me too similar to @jeltz and @alexanderp with the following error

pkg_resources.DistributionNotFound: The 'async-timeout<3.0.0' distribution was not found and is required by gns3-server

Since the last update I'm having the same problem as alexanderp has. Apparently GNS3-server requires python-async-timeout to be version 2.0.1-1 or lower.

Since the update, gns3server throws this error:

pkg_resources.ContextualVersionConflict: (async-timeout 3.0.1 (/usr/lib/python3.7/site-packages), Requirement.parse('async-timeout<3.0.0'), {'gns3-server'})

I had an issue with some missing python stuff when trying to start this after the most recent update. Using "pip3 install gns3-server" and "pip3 install gns3-gui" like recommended on the GNS3 site solved it.

I workarounded the aiohttp-cors issue by installing it with: pip install aiohttp-cors==0.5.3

I've make symlinks to /usr/lib/python3.7/site-packages and gns3-server starts.

GNS3 still don't run on my comp. python-async-timeout-gns3 is installed in /usr/lib/python3.6/, actual version of python is 3.7. Ina trace back I see "pkg_resources.DistributionNotFound: The 'aiohttp-cors<0.6.0,>=0.5.3' distribution was not found and is required"
