I suspected another mistake, in particular I suspected that I
didn't remember correctly and "apt-get install ./local_package.deb"
doesn't work at all. However, not that long ago dpkg -i + apt-get -f or
alternatively gdebi needed to be used. Some day apt install replaced the
dpkg -i + apt-get -f/gdebi approach.
Much likely "apt-get install ./local_package.deb" to resolve
dependencies by repos is relatively new to apt-get.
