Jetpack 4.4 Visionworks on Host install fails

I am trying to install Jetpack 4.4 on my TX2 by using sdkmanager 1.2.0.
The install of Visionworks on Host fails every time with an install error.

Hi mtbsteve,

From the log, the visionworks repo is broken on your host system. You need clean up all visionworks residues on your host then retry.
Please use following steps:

  1. Run sudo dpkg -l | grep visionworks to list all visionworks packages.
  2. Run sudo dpkg --purge <visionworks_package_name> to remove the listed visionworks packages one by one.
  3. Reinstall with SDK Manager.

Thanks! That solved the issue.
