对于仍然遇到此错误的任何人，我发现这是由于Xenial到Bionical的升级导致PPA徘徊，我想这里缺少一个依赖项。这正是我为修复它所做的事情。
sudo rm /etc/apt/sources.list.d/gns3*
sudo apt-get update
sudo add-apt-repository ppa:gns3/ppa
sudo apt-get update
sudo apt-get -y -u dist-upgrade
然后您可以启动gns3。

在将Ubuntu升级到20.04之后，我得到了这个。唯一有效的方法是使用项目文件备份GNS3文件夹，然后卸载gns3-server和gns3-gui，然后重新安装。现在一切正常。
