Arch Linux User Repository

@corneabogdan84, please don't give stupid advice to others.

Downgrade python-sentry_sdk to 1.9.0 and wait until python-urllib3 gets updated.

And for jsonschema edit gns3-gui and gns3-server PKGBUILDs and add to sed:

-e 's|^jsonschema==3\.2\.0|jsonschema>=3.2.0|' \

@derdeagle I got it working by using pip to update urllib3.

I, too, get this error message shown after updating. But this is not the only error message, the next one is:

The required version was released on July 25 2022 (13 days ago today). The arch repo does not yet include this version.

Doesn't work for me after updating python-jsonschema from 3.2.0-6 to 4.9.0-1.

@Mario156090, just update PKGBUILD and rebuild python-util package yourself. All you need to do is change pkgver/pkgrel.

Well, the last version for psutil is 5.9.1 and GNS3 require this but Arch official repository does not update yet.

So, I found a Workaround for this.

First, uninstall gns3-server and gsn3-gui. second, install pip3 package. third, install the pip3 version package of psutil, use this command: python -m pip install --upgrade --no-cache-dir --use-deprecated=legacy-resolver psutil

fourth, reinstall gns3-gui and gns3-server.

Good luck people!

Yes, python-psutil needs to be updated, but I can't do anything about that.

waiting update python-psutil >=5.9.1

Much appreciated. Launches now.

kazaii: Thanks, that was a typo (‘<’ instead of ‘>’) – fixed.
