Handling SUSE build key renewal

This document (000019805) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 15
SUSE Linux Enterprise Server 12


In October 2020, the GPG key used the verify the repository signatures of SUSE Linux Enterprise 12 and 15, was a adjusted from 2020, to 2024.

This change was delivered via suse-build-key package updates, and also via repository keys refreshes in the Update repositories (see Additional Information):

There are rare cases where this update did not refresh the RPM keyring, e.g. if you refresh all repositories all the time.
In this case there was a bug in libzypp which prohibited the automatic refresh of the key.


When encountering this behavior, you can resolve this using either one one of these two options below once :
  • zypper refresh only one of the update repositories
this will refresh the zypper keyring.
  • manually refresh the new gpg key from suse-build-key as root:
rpm --import /usr/lib/rpm/gnupg/keys/gpg-pubkey-39db7c82-5f68629b.asc
  • Alternatively, the following command (as root) can be executed which will manually trigger a refrsh
zypper lr -E | grep Updates | awk -F\| '$4 ~ /Yes/{gsub(/ /,"",$2);print $1;exit}' | xargs -r zypper ref -f -r


The GPG signing key for the SUSE Update repositories was close to expire.

Additional Information

Updates were released as per the following :

In addition, also the GPG key for the various SLE media has now also expired.
For example:
  • SUSE Linux Enterprise Server 15 SP2
  • SUSE Linux Enterprise Server 15 SP1
  • SUSE Linux Enterprise Server 15 GA
In case official SUSE media with the updated GPG is required for any offline deployments, SUSE suggests to download the QU Media ISO instead. These Quarterly Update releases contain all maintenance updates of the packages that have been released in the meantime

The QU (Quarterly Update) ISO's can be downloaded from the the regular SUSE Download page, and can be identified as quarterly update by their name.  For example SLE-15-SP2-Full-x86_64-QU1-Media1.iso and SLE-15-SP1-Installer-DVD-x86_64-QU5-Media1.iso
