18 Using Dell Update Packages
4 Obtain the Linux DUP and its associated signature file from the
Dell Support website at
support.dell.com/support/downloads .
NOTE: Each Linux DUP has a separate signature file, which is displayed along
with the DUP. You need both the DUP and its associated signature file for
verification. By default, the signature file is named the same as the DUP
filename with a .sign extension.
5 Verify the DUP using the following command:
gpg --verify <Linux Update Package signature
filename> <Linux Update Package filename>
Executing DUPs in the Windows Environment:
To run DUPs from the interactive graphical user interface (GUI), perform the
following steps. This procedure applies to all Update Packages.
1
Execute the DUP by double-clicking the filename from within Windows
Explorer.
2 Read the update information displayed in the DUP window.
3 Click Install to install the DUP.
4 Reboot the system, if necessary.
To execute DUPs from the command line interface (CLI), see "Command
Line Interface Reference" on page 31.
Verifying the Digital Signature
A digital signature is used to authenticate the identity of the signer of an
Update Package and to certify that the original content is unchanged. Digital
signature of DUPs gives you a more reliable and trustful method of
authentication.
Verifying the digital signature ensures that the original Update Package was
received correctly and that the content has not been modified since it was
signed.
To verify the Update Package’s digital signature, perform the following steps:
1
Start Windows Explorer and locate the Update Package whose digital
signature you want to verify.
2 Right-click the filename.
