I want to use the blackboard letters which match the Computer Modern font from the cmathbb font package. The above code (from here) does not compile and I get the following errors in the output.

Edit: Upon reading the comments, it seems that this is a bug in the package, for Linux. The code compiles without any problems on Windows; I don't know about MacOS.
