Do you have any other leaf switch upgraded successfully?
what is the APIC version,
there is bug around kind of issue : (not sure is that effecting) worth looking if that solves.
is the compatibility checked?
yes there are 4 other leaves of the same type and upgraded successfully.
but after we add two remote leaves and tried to upgrade it to the same version as the APIC (14.2.4k) this error appears.
Did you get this resolved?
There is a OSPF Authentication bug with remote leaf in the 4.2.4 train
