Hi @czoido

I don't think this should be handled here, but much sooner. Here it is too late, and there are other things that could cause a NotFoundException (e.g. trying to download a .zip for the conan config install).

It is the exception itself who should encode a better error message as close to the raise as possible, by the one that has the context (remote_name, ref, or whatever makes sense)

Much better. Please also add a test, or an extra check to an existing test, and it could be merged. Thanks!

try:
ref = remote_manager.get_recipe(ref, remote)

You can skip the check of 404, you already got that exception. It is ok to re-raise it with a new message.

Check the broken test: https://conan-ci.jfrog.info/blue/organizations/jenkins/ConanTestSuite/detail/PR-5399/3/pipeline

Also, consider adding a new test or a new check in existing test for the download command behavior.
