Article Applicability

This article is specifically regarding the Veeam Hardened Repository ISO v2 appliance, which was distributed alongside Veeam Backup & Replication 12.

For information about manually updating the GPG key on the appliances associated with Veeam Backup & Replication 13, review KB4834.

Challenge

This article documents how to manually update the GPG key for Veeam Hardened Repository ISO v2 appliances.

Generally, the new key should automatically be distributed to all appliances that have access to the Veeam repository. However, if the appliance does not have access to the repository (either directly, via a mirror, or via http_proxy), the GPG key will not be updated. After the installed GPG expires, that appliance will be unable to connect to the update repository.

On March 15, 2026, the GPG key used to sign the Veeam RPM packages expired.

Solution

  1. Download the new GPG key and copy it to the Veeam Hardened Repository either via the Files node or via SSH using the veeamsvc account.
    The new key is available here:
    https://repository.veeam.com/keys/RPM-E6FBD664
  2. Use Live Boot ISO to gain shell access to the Veeam Hardened Repository appliance.
    Live Boot is available from the same ISO used for installation.
  3. Once in live boot, mount the original system disks and enter chroot.
  4. Delete the old GPG key using the following command:
rpm -qa gpg-pubkey | grep e6fbd664 | xargs -r rpm -e
  1. Import the new GPG key using the following command:
rpm --import /path/to/new/gpg_key
After importing the new GPG key, updates from the repository should be available again.
