    Hello!

    I tried to downgrade JunOS on qfx5100-48t-6q from 20.4R3-S3.4 to 18.4R3.3 version and got the following error:
    THIS IS A SIGNED PACKAGE
    ERROR: /usr/libexec/ui/downgrade: a legacy Junos installation package is required...

    I had done downgrade successfully a few times before I got this error
    Does anybody know how to solve it?
    Thanks!

    Hi,

    in the past I got the same error and the cause was the wrong date of device. Try to fix the date manually (from CLI "set date ...").

    Regards
