Cannot update with slackpkg+

Hi,

I just reinstalled Slackware64 using this current ISO (https://slackware.uk/people/alien-cu...64-current-iso).
So it's a fresh install, but unexpectedly slackpkg+ is not working. I'm using slackpkg+-1.7.6-noarch-5mt
I set verbose at level 3 on slackpkgplus.conf
If I run slackpkg update gpg, I got this:

Code:Getting key from https://www.slackware.com/infra/keys/GPG-KEY
Slackware Linux Project's GPG key added

==============================================================================
INFO! Debug informations
------------------------------------------------------------------------------
https://www.slackware.com/infra/keys/GPG-KEY --> OK
The temp directory /tmp/slackpkg.cjME7y will NOT be removed!
==============================================================================Then I run slackpkg update, and I got this:

Code:FATAL! No Slackware GPG-KEY imported.
If you are upgrading from an older release of slackpkg+, all keys must to be reimported.
Please run
# slackpkg update gpg

==============================================================================
INFO! Debug informations
------------------------------------------------------------------------------
The temp directory /tmp/slackpkg.0C5RO6 will NOT be removed!
==============================================================================How is it possible? I have never had issues with slackpkg update gpg and slackpkg update commands.
How can I solve?
If I disable slackpkg+, slackpkg is running fine.

Thank you in advance,
