When i type mcpelauncher ,i have three complete : 1,mcpelauncher-client ,2,mcpelauncher-server and 3,mcpelauncher- ui-qt I dont know how to begin, so i open one by one , but no one can run. I guess 3 is the mainly launcher. Below 1,2,3 represent client, server, ui-qt

NOTE: pacman cannot update an AUR package source at all. mcpelauncher-msa-git mcpelauncher-msa-ui-qt-git mcpelauncher-linux-git mcpelauncher-ui-git are build from source every time you build the AUR package (same version)

mcpelauncher-ui-qt is the right to start, but you updated protobuf via a system update, but you kept the old mcpelauncher-ui-qt which needs the old removed protobuf version.

Using the appimage avoids this problem
