You see a message in Calamares and you did not change anything.
Maybe Calamares did not change
Maybe the configuration did not change
but everything else did change.
New kernels, new systemd and also the packages that are needed to make Calamares work.
Here the two packages that cause this message is boost and boost-libs.
Do not look any further. If you did not change your configuration of Calamares then that is not the reason for this message.
Just rebuilt Calamares against the new boost and boost-libs.
That is all.
Put this build on your local repo and start getting independent from anyone.
