Troubleshooting DSU

Repository conflicts for updates having different

version.

DSU hovers over incorrect updates, if multiple repositories are configured which contains different versions of similar packages.

It is recommended to disable other repositories in such cases.

DSU not recognized after installation

After installation of DSU, when you try to run DSU commands on host or remote system, the following error message is displayed: "Dsu is

not recognized as internal and external command"

On the freshly installed Operating System, when user runs DSU commands, DSU is unrecognized due to delay (approx. three minutes) in

updating environment variables. Post the update, DSU works as expected.

Workaround:

• Refresh the PATH environment variable by deleting and reentering the PATH value and click apply from the System settings. Open a

new command prompt window, and try the DSU commands.

• Reboot the host system after installation.
