I want to update my APP for the course PhoenixLiveView with Pragmatic Studio and when I try to do a mix hex.outdated it complains Update not possible for some libraries as you can see:

Run `mix hex.outdated APP` to see requirements for a specific dependency.
To view the diffs in each available update, visit:
I want to try the command mix deps.update.
But first I want to ask here how to properly update these libraries.
Someone can help me with this please?

“Update not possible” mean that constraints in direct or indirect dependencies are preventing upgrade. For example if some library requires inflex =2.0.0 then there is nothing you can do unless that dependency updates their constraint. Of course you can override deps, but that can cause breakages in that dependencies due to incompatibility.

So If I update it’s possible to take errors.
So you recommend do nothing?
Or I need to read the evolution of the version library and make some changes?
For these… updating Phoenix to 1.5.7 should make them available for update
The command will consider the restrictions in your mix.exs file.
When you run mix dips.update --all, it will upgrade all versions labeled as “Update possible”.
For instance, say you have {:phx_gen_auth, "~> 0.5.0"} in your mix file.
After you run mix hex.outdated you’ll see:
Dependency Current Latest Status
phx_gen_auth 0.5.0 0.6.0 Update not possible
In this case, the update is not possible because in the mix file you specifically restricted the upgrade to 0.5 versions, it would update to 0.5.x as 0.5.2 or 0.5.9 but it won’t upgrade to 0.6.x.
So you might want to relax your dependencies a little bit.

Sorry guys, what I need to do now?
The path for the commands to update was ok?
So now how I need to do for upgrade the phoenix_live_view?

Sorry I was wrong and You also need to change your versions in mix.exs as well, as mentionned by @shamanime
Try to change your mix.exs to
dashboard → 0.4
live_view → 0.15
then mix deps.get and mix compile…

This link Version — Elixir v1.11.3 has a little bit more information about what the symbols before the versions specified in the mix.exs file do.
When I changed these versions for {:phoenix_live_view, "~> 0.15.4"}, {:phoenix_live_dashboard, “~> 0.4.0”}`` ElixirLS tells this error on Visual Studio Code:
an exception was raised:
** (Mix.Error) Can't continue due to errors on dependencies

No quick fixes available
So I tried to update even with those errors doing mix deps.get and mix compile…
It was needed to restart the ecto and the app phoenix liveview are working right and passing the tests.
But The ElixirLS continues raising this error…
Thank you all for the help, it was very helpfull!
I have bad experienced with vscode aggressively changing my dependencies.
Now, I stop vscode and use vim when I update.
Try removing .elixir_ls/ manually, it will be rebuilt next time You open vscode.
Try removing _build and recompile.
I know a little bit Vim but I need to learn more…
Wich libraries are recommended for elixir?
I have in my plans to read some book…
So I deleted and the errors continue but it’s working the app and the tests pass.
The auto fetching of deps can be disabled in the settings.
