Xelatex: Shared Library Error

[xfallme]

I am running the Dockerfile like this:

FROM qmcgaw/latexdevcontainer:latest-full

to get full access to xelatex as compiler, but when I try to create the PDF, I get this error:

[FROM qmcgaw/latexdevcontainer:latest-full qmcgaw/latexdevcontainer:latest-full](xelatex: error while loading shared libraries: libfontconfig.so.1: cannot open shared object file: No such file or directory)

[qdm12]

I think you're just missing fonts, if you run

apt update
apt install libfontconfig1

does it resolve it?
