Error: package ‘StanHeaders’ 2.18.1 was found, but > 2.18.1 is required by ‘rstan’

I am writing an R package that depends on Stan and Rstan. I run the installation on an Azure machine Standard_D64_v3 and install r-base and r-cran-stan with sudo apt-get and rstan and Rcpp with R's install.packages()(among others, see shell setup script and R setup script).

This process worked OK last month. Today I was able to install the package (as evidenced by the welcome message) and then have a runtime error from incompatible versions.

...

Welcome to PosteriorBootstrap, a parallel approach for adaptive non-parametric learning
Error: package ‘StanHeaders’ 2.18.1 was found, but > 2.18.1 is required by ‘rstan’
In addition: Warning message:
version 2.18.1.10 of ‘StanHeaders’ masked by 2.18.1 in /usr/lib/R/site-library 
Execution halted

I do not have StanHeaders anywhere in my code so I suspect the problem is between different packages. How can I solve this problem with versions?

As @nicola wrote in the comments, the fix is to reinstall StanHeaders with:

install.packages("StanHeaders")

The previous code may have stopped working because of a new version of R, but I could not determine the cause.
