Hello team,


I have a problem with my export configuration Panorama via  scheduled task.

When I make a test SCP server connexion I have this mesage : 




Before upgrade to 10.2 the export was working fine.

I have also saw that PAN-188052 talk about this issue. Do you know how to fix it ? 

Could you help me please tu understand this problem.


Thank you in advance.

I had this issue under the same circumstances and TAC were also able to resolve it by logging in as root and manually removing the old key, so it may be worth asking them to try for you.

The known issue id is PAN-194805. Probably fixed in March 10.2.4 release. A mentioned, in the meantime, you can contact support and have them login to root.

Seem also still be an issue  in 10.2.3-h4,   but i also don't see the bug id back in the know issue list.

Does anyone know under which bug id this will be fixed and also in which release?

We hit this issue again after having it fixed, but following the H4 patch installation.  We are still working on the understanding that hit will be resolved in 10.2.4
