route::get("/profile/edit", [

]);
route::get("/profile/{slug}", [
"uses" => "ProfilesController#index",

]);
});

Answer 1

From your question, i can understand that you're trying to update a profile using POST method or may be PUT method earlier. Since, the resource you are editing is unique, you're not passing any parameters for the controller to find that single resource so as to update it.
therefore modify your your route like
route::put("/profile/update/{id}", [
"uses" => "ProfilesController#update",
"as" => "profile.update"
]);
And your form like
<form action="{{route('profile.update', ['id' => $id])}}" method="post">
#csrf
#method('put')
You'll need to pass the ID of the profile you want to update as parameter
then at the controller
public function update(Request $request, $id){
//edit the profile with id = $id
}

Answer 2

You have an error in your form definition
<form class="{{route('profile.update', ['id' => $id])}}" method="post">
should be
<form action="{{route('profile.update', ['id' => $id])}}" method="post">

Answer 3

Since you made a form for PUT request, you have to change
route::post("/profile/update/profile", [
"uses" => "ProfilesController#update",
"as" => "profile.update"
]);
to this
route::put("/profile/update/profile", [
"uses" => "ProfilesController#update",
"as" => "profile.update"
]);

Here is the correction in your provided example.
In form route('profile.update', ['id' => {here you have to place id of record which you want to update}]).
View File
$info->id])}}" method="post">
<div class="form-group">
<label for="location">Location</label>
<input class="form-control" type="text" name="location" value="{{$info->location}}">
</div>
<div class="form-group">
<label for="about">About</label>
<textarea name="about" id="about" rows="10" cols="50" class="form-control">{{$info->about}}</textarea>
</div>
<div class="form-control">
<p class="text-center">
<button class="btn btn-primary btn-md" type="submit">Update Your Info</button>
</p>
</div>
</form>
</div>
In Route
Route::group(["middleware" => "auth"], function(){
route::get("/profile/{slug}", [
"uses" => "ProfilesController#index",
"as" => "profile"
]);
route::get("/profile/edit/profile", [
"uses" => "ProfilesController#edit",
"as" => "profile.edit"
]);
route::post("/profile/update/profile/{id}", [
"uses" => "ProfilesController#update",
"as" => "profile.update"
]);
});
In Controller
public function update(Request $request, $id)
{
dd($id, $request->all());
}
