Uninstalling KAE Installed Using DEB Packages

This section describes how to uninstall KAE that is installed using DEB packages if you no longer require it or want to install KAE of a new version. Due to the dependency relationships, the hisi_hpre and hisi_sec2 driver packages must be uninstalled before the UACCE driver package is uninstalled. The libkae engine package must be uninstalled before the libwd driver package is uninstalled.

Procedure

  1. Use an SSH tool to remotely log in to the Linux CLI as the root user.
  2. Uninstall the KAE software packages and check the uninstallation result.
    1. Uninstall the KAE software packages.
      Run the dpkg -r Software_package_name command. For example, run the following command to uninstall hisi_sec2:
      1
      dpkg -r hisi-sec2
    2. Run the following command to check whether the software packages are successfully uninstalled.

      Run the dpkg -L Software_package_name command. For example, run the following command to check whether hisi_sec2 is successfully uninstalled:

      1
      dpkg -L hisi_sec2

    The following uninstalls all KAE software packages:
