There is absolutly no way for pkg to discover that because default python was changed to python 3.11 then those package should now be named py311-mutagen and py311-matrix-synapse. Which means the solver will current propose to remove them and all they depend on, as they do not exist anymore in remote repositories, or if we have stronger rules than we have now pkg will die in a non solveable situation and let the user try to figure out what should be done. This is our role as ports committers to find something which don't let users be trapped in such situation. Best regards, Bapt
