Manjaro no updates
Knowing that this a is a Arch forum (Manjaro depends on Arch):
After having installed Manjaro 0.86 Mate 1.6 I tried to update the system.
Because Manjaro Mate comes with both BT managers (Mate and blueman) and BT does not work in many Mate editions, I deleted Mate BT manger and wanted to update. But an error message appeared.
