missing dependencies on i386 systems for xskat (xfonts-base)

xskat was installed in Lubuntu 18.04 i386 (the error does not occur on amd64-installations).
After starting it, the error

Font 10x20 not found

occurs.
The solution is to install the package xfonts-base and run
sudo dpkg-reconfigure fontconfig

Might it be a missing dependency?
