Qt MaintenanceTool : Failed to connect to server.

  • Hi, I'm using Deepin (Linux) and Qt 5.9.3. I wan to remove Qt. When I run MaintenanceTool, I see this: Failed to connect to server. Check your network connection and try again.. I can't remove Qt. What is the reason? Thanks.

  • Just delete /opt/Qt or whatever directory your installation is in.
