Error with DS 4.0 prerequisites on Nano

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

This is on the Nano

After finishing with the SDK Manager, but before installing DS 4.0,
it seems that gstreamer is already installed.

gst-inspect-1.0 version 1.14.1
GStreamer 1.14.4

I deleted the gstreamer cache and ran gst-inspect-1.0. Perfect, no problem.

Then following the DS 4.0 instructions I did this:

$ sudo apt-get install
libssl1.0.0
libgstreamer1.0-0
gstreamer1.0-tools
gstreamer1.0-plugins-good
gstreamer1.0-plugins-bad
gstreamer1.0-plugins-ugly
gstreamer1.0-libav
libgstrtspserver-1.0-0
libjansson4

This resulted in

gst-inspect-1.0 version 1.14.4
GStreamer 1.14.4

I deleted the gstreamer cache and ran gst-inspect-1.0.

I got

(gst-plugin-scanner:2885): GLib-GObject-WARNING **: 10:05:59.806: cannot register existing type ‘GstInterpolationMethod’

(gst-plugin-scanner:2885): GLib-GObject-CRITICAL **: 10:05:59.806: g_param_spec_enum: assertion ‘G_TYPE_IS_ENUM (enum_type)’ failed

(gst-plugin-scanner:2885): GLib-GObject-CRITICAL **: 10:05:59.806: validate_pspec_to_install: assertion ‘G_IS_PARAM_SPEC (pspec)’ failed

followed by normal output.

This is before any DS 4.0 specific files were installed.

It comes from nvvidconv.

If background updates happen successfully in the background immediately after the end of flashing (unattended-upgr), then the first invocation of gst-inspect-1.0 (after deleting cache) is enough to show the warnings.
