ok @salton , Now I understand.
I noticed you coming from Spacewalk as many of us, unfortunately, there’s no support for errata on debian-like systems, for now. There’s an ongoing initiative, many posts asking for the same and many dependent things around this, take for example: Ubuntu Foreman/Katello Not showing Applicable Packages
I feel it won’t be that long until completed, but if you are in an urgent situation, maybe looking for a temporary alternative is not a bad idea.
