R - failed package installation with github dependency

I want to install a package that has a github dependency. The DESCRIPTION

package file says:

Imports: ggplot2, ggthemr
Remotes: cttobin/ggthemr@0b2e7da43d4d2844b08b039510b31078

      

        
        
        
      

    

However, when I try to install the package, the automatic installation of the package ggthemr

from github as a dependency fails without any informational error message. It looks like he was trying to install a CRAN dependency instead of github.

The PACKAGES

repository file where I want to install the package from (a drat

repo) has Import specified, no bullets. Adding the Remotes line manually does not solve the problem.

Any help is appreciated.
