The following packages have unmet dependencies:
sbuild-build-depends-main-dummy : Depends: python3-skimage but it is not

apt-get failed.
E: Package installation failed
Broken build dependencies are often FTBFS in a build dependency,
and it creates extra work having to manually merge such bugs.
Please check why a build dependency is no longer installable before
opening such bugs.

skimage has uploaded a new version that drops the dependency on
python3-pydata-sphinx-theme for the time being:
