** Description changed:
+ [ Impact ]
+
+ * The update to ubuntustudio-default-settings 22.04.26.1 caused an
+ unforeseen regression in which the SDDM theme failes reproducibly. This
+ is due to the replacement of a symlink of Main.qml in the SDDM theme
+ that should point to the Breeze SDDM theme no longer existing and being
+ replaced by a physical file when it should not have been.
+
+ * It is notable that this did *not* show up in the debdiff of the
+ upload [1], nor does it show up anywhere in the git history. This does
+ seem like a strange anomaly, to which the cause is unknown.
+
+ * To resolve, a new version of this is uploaded and needs expedited
+ approval to fix this regression.
+
+ [ Test Case ]
+
+ * Install Ubuntu Studio 22.04
+
+ * Completely upgrade
+
+ * Restart
+
+ * SDDM theme will be broken
+
+ [ Where things could go wrong ]
+
+ * At this point, I have little faith in the .debdiff to show if the
+ symlinks have been replaced with physical files, so I suppose this could
+ happen. However, I have checked the source tarball prior to upload to
+ make sure, and all 0kb symlinks seem to be in-place.

+ Original bug report:
+
Steps to reproduce
1) Install Ubuntu Studio 22.04. Completely default install (whole disk, etc)
2) Boot into new install
3) Install all updates and reboot
You get an unfamiliar looking login screen and an error message "The current
theme cannot be loaded due to the errors below, please select another theme"
file:///usr/share/sddm/themes/ubuntu-theme/Main.qml:204:17: Cannot assign to
non-existent property "actionItemsVisible"
Through process of elimination, determined that of the 345 packages
installed in step 3, ubuntustudio-default-settings causes the problem.
