Can't install the NVIDIA SDK manager. Need to deprecate from Jetpack 4.6.2 (L4T 32.7.2) to Jetpack 4.6 (L4T 32.6.1)

[odode2019]

So i have been following the steps given in NVIDIA SDK Manager | NVIDIA Developer

I successfully downloaded the .deb file but for some reason when i go to install the package using the command line
sudo apt install ./sdkmanager_[version]-[build#]_amd64.deb

in terminal, i get this error -

protodromics@protodromics-desktop:~$ sudo apt install ./sdkmanager_1.8.4-10431_amd64.deb
Reading package lists… Done

Note, selecting ‘sdkmanager:amd64’ instead of ‘./sdkmanager_1.8.4-10431_amd64.deb’
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
sdkmanager:amd64 : Depends: libgconf-2-4:amd64 but it is not installable
Depends: libcanberra-gtk-module:amd64 but it is not installable
Depends: locales:amd64 but it is not installable
E: Unable to correct problems, you have held broken packages.

I’m not sure how to solve this. My details are -

Hi,

I am not sure what you are doing here. Why are you telling me the environment of your jetson while you are asking the problem of installing sdkm on host machine?

Sdkmanager needs to run over x86_64 host.

I have a similar thought regarding:
Depends: locales:amd64 but it is not installable

The question is why it is not installable, since this is rarely a problem. My thought is that this is either the Jetson (which is not amd64) and thus not the intended place to install JetPack/SDKM, or it is related to the locale on your system. Are you installing to a desktop PC?
