Elastic Agent No upgrade option Available

[Anabella_Cristaldi (Anna)]

Hi all,
I have a problem with some agents. I'm in version 7.16.1, I was able to upgrade most of my agents, but for some I have no option to upgrade..
The target systems (were the agents are installed) are redhat linux 7.4
Someone seen something like this?

Also, inspecting the Fleet Agent's internal indices I found this for the agents with no upgrade option available

Thank you!

The problem is that installing the Linux agent via RPM.
If you use the .deb/rpm installation method there is no way to update via fleet.
There is a note in the installation instructions in the Fleet'sUI
I've missed that.

Thank you @Rasmus_Breinholm_Rom
