Re: GNS3 cannot be used after installation

Please don't bump.

Also, please use code tags.

Mod note: Moving to AUR Issues.

Re: GNS3 cannot be used after installation

https://aur.archlinux.org/packages/gns3 … ent-725861
Upstream does not support yarl 1.4+ because that would require python 3.6+
https://github.com/GNS3/gns3-server/com … fb50e8d0c4
PKGBUILD could change the requirement.
