This release addresses an issue with amd64 installs (LP: #2033977) where the security pocket in sources.list can end up not configured matching documented best practices. It is recommended to configure the $series-updates to come from security.ubuntu.com, to minimize the effect of mirroring delays.

Affected systems will be AMD64 systems installed with Ubuntu 23.04, 22.04.3LTS, or installs done since April 2023 that accepted the snap version update.

To correct systems already installed, please modify /etc/apt/sources.list, look for the lines containing -security, and update them to use http://security.ubuntu.com.

"Ports" architectures (everyone but amd64) should not be affected by the above issue and should pull security updates from http://ports.ubuntu.com
