Package: upgrade-reports Severity: normal The described issue can be reproduced on a fresh bullseye install made through the latest official bullseye installer. The issue only concerns the KDE Plasma desktop environment version of Debian.
My previous release is: bullseye I am upgrading to: bookworm Upgrade date: 17.6.2023 Method: Minimal upgrade steps according to https://www.debian.org/releases/bookworm/amd64/release-notes/ch- upgrading.en.html Contents of /etc/apt/sources.list: untouched, except changing "bullseye" to "bookworm" in order to upgrade. - Were there any non-Debian packages installed before the upgrade? If so, what were they? No - Was the system pre-update a 'pure' system only containing packages from the previous release? If not, which packages were not from that release? Yes, fresh install directly from official installer. - Did any packages fail to upgrade? No - Were there any problems with the system after upgrading? Yes, see below Further Comments/Problems: A fresh Debian 12 Bookworm installation (directly from the official installer) with the KDE Plasma desktop environment uses the pulseaudio server as a default audio middleware, but when upgrading from a fresh "off-the-shelf" Debian 11 Bullseye to 12 Bookworm (with the steps as advised by https://www.debian.org/releases/bookworm/amd64/release-notes/ch- upgrading.en.html) pipewire-pulse and wireplumber get installed automatically (apparently per suggestion by package plasma-pa) and replace pulseaudio from there on. Pulseaudio remains installed, only being suppressed by pipewire-pulse. I noticed this first on my own private Debian installation, where I recently upgraded. I was also able to reproduce this on a fresh Debian 11 Bullseye install where I then upgraded to Bookworm. (according to upgrade guidelines) This behavior does not break system sound or usability as far as I can assess, but since it does deviate from the default KDE Plasma setup that you get from installing Debian Bookworm directly from installer rather than upgrading to it, as well as changing the sound server from pulseaudio to pipewire without informing or asking the user, I assume this is still unwanted behavior and hence a bug. Best regards.
