the error here is that the snap command does not tell you that "snap list" can not take arguments and then falls back to a confusing message instead ...

try just "snap list" that should show your installed mongodb ... (or did you mean to search for mongodb in the store ? that would be "snap find mongodb")

"snap list" can take arguments; the error message is wrong when you give it an argument that doesn't match an installed snap though:

$ snap list
