Deleted or changed the Public key
When user deletes or changes the Public key.
Workaround: Download all the .asc files from https://linux.dell.com/files/pgp_pubkeys/ and add it under the working
directory /usr/libexec/dell_dup folder.
Unable to update the servers from user created repository
Unable to update the servers from user created repository using --source-type=REPOSITORY, --source-location and
--catalog-location
Workaround: when --source-type and --source-location is used, user is recommended to use catalog file as
"catalog.xml" in the source location
when --source-type , --source-location and --catalog-location is used, user is recommended to provide full
name of the catalog.
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.
Unable to recognize DSU 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"
Workaround:
● Ensure that all the mentioned prerequisites are met .
● 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.
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.
DSU exit with an error message
The following error message is displayed "Symbolic link detected [C:\ProgramData\Dell\DELL EMC System
Update\Log.txt]"
Workaround: DSU does not allow symbolic link files (like Log.txt) by default , unless user provides it explicitly.
"Unknown option provided in DSU" error message while
performing DSU options
When user tries performing any DSU options on remote system, user is prompted with an error message.
Workaround: Recommended to use the latest DSU version on remote system as well.
