    Problem solved!

    It was necessary to add no-validate, that is to say:
    request vmhost software add /var/tmp/junos-vmhost-install-mx-x86-64-21.2R1.10.tgz no-validate

    > show version
    Hostname: jRT201.DC
    Model: mx204
    Junos: 21.2R1.10
    JUNOS OS Kernel 64-bit [20210529.2f59a40_builder_stable_12]

    Hello

    I faced the same issue on MX204
    My path upgrade was: 19.4R3-S1.3 (initial version)----1step----> 20.2R3-S5.6 ----2step------> 20.4R3-S4.8 ----3step-----> 21.2R3-S2.9

    My first step (1step) and second step (2step), the command below help to upgrade
    request vmhost software add /var/tmp/junos-vmhost-install-mx-x86-64-20.xRx-Sx
    But the last step (3step) no-validate was mandatory to upgrade successfully (without no-validate at the end, the upgrade was failling with this error

    ERROR: Require 12 kernel support

    Validation failed
    ERROR: Failed to add /var/tmp/junos-vmhost-install-mx-x86-64-21.2R3-S2.9.tgz
    warning: Host software installation has failed.

    Do you know why we have this behavior ?

    Thank you.

    Just was reading this as I run int to the same problem. Do you know if you can do upgrade straight to the desired JunOS i.e: if the RE is factory new skipping the intermediate hop?

    I've only gotten it to work by downloading the image rather than the installer, adding it to a usb drive, and booting from that.
