Unable to install Salt native minion on vQFX: malformed package

[ggiesen]

Salt has recently open-sourced their Junos native minion (https://saltstack.gitlab.io/open/docs/salt-install-guide/topics/install/native/juniper.html) but it does not install on vQFX10k running 20.2R1.10:

root@vqfx-re> request system software add /var/tmp/salt-junos-x86-64-20201026-235317.tgz                      
malformed package: /var/tmp/salt-junos-x86-64-20201026-235317.tgz

For comparison, it runs just fine on an MX204 running 18.3R1.9:

FYI the code was developed / tested / released with the use of a QFX 5120 running v18.4. Also it was additionally tested by Juniper too as part of a co-development.

Also tested on vQFX running 18.4R2-S2.3 and had the same issue
