I have plugin that notify some packges should be updated:

using dnf update 
or dns upgrade
it does not find anything:

# dnf update

2015. Dependencies resolved.
Nothing to do.

then I do a clean all
--------------------
# dnf clean all

That one doesn't use "dnf" but PackageKit as a backend. You would
need to compare with the "pkcon" tool, not "dnf".

Please! For years, Yum users have thought they would "need" to run a
"clean all" when all they really wanted was "clean metadata" only.
It's the same with DNF. Consult the manual page. There are enough
commands available that would make DNF delete the local cache and
redownload metadata from the repo. Notice "dnf clean expire-cache" and
"dnf clean metadata" and also the "dnf --refresh …" option to add
to any command.

Also look up "dnf clean all" to understand what it does.
