Verify Dell digital signature

Instructions taken from here:

Download the Dell Linux public GnuPG key, if you do not already have it, by navigating to and clicking the Dell Public GPG key link. Save the file to your local system. The default name is linux-security- publickey.txt.

  • Import gpg key to your trusted database. gpg –import linux-security-publickey.txt
  • To avoid distrust warnings, change the trust level for the Dell Public GPG key: gpg –list-keys

pub   1024D/23B66A9D 2001-04-16

uid                  Dell, Inc. (Product Group) <>

sub   1024g/10C11901 2001-04-16

  • gpg –edit-key 23B66A9D
  • From within the gpg command editor, type fpr
  • The following message appears:

pub 1024D/23B66A9D 2001-04-16 Dell, Inc. (Product Group) <>
Primary key fingerprint: 4172 E2CE 955A 1776 A5E6 1BB7 CA77 951D 23B6 6A9D

If the fingerprint of your imported key is the same as above, you have a correct copy of the key.

While still in the GPG key editor, type trust. The following menu appears:

  1. lease decide how far you trust this user to correctly verify other users’ keys (by looking at passports, checking fingerprints from different sources, etc.)

    1 = I don’t know or won’t say
    2 = I do NOT trust
    3 = I trust marginally
    4 = I trust fully
    5 = I trust ultimately
    m = back to the main menu

    Your decision?

      1. Type 5 <Enter>. The following prompt appears:

    Do you really want to set this key to ultimate trust? (y/N)

      1. Type y <Enter> to confirm your choice.
      2. Type quit <Enter> to exit the GPG key editor.
  • Verify the Update Package:

gpg –verify <Linux Update Package signature filename>.sign <Linux Update Package filename>
