[Pkg-fonts-devel] Bug#816965: fonts-mathematica: fails to install if mathematica-fonts 17 is installed

[Julian Gilbey]

Package: fonts-mathematica
Version: 18
Severity: serious

When trying to install, I get the following error message:

Preparing to unpack .../fonts-mathematica_18_all.deb ...
The license has already been accepted
Unpacking fonts-mathematica (18) ...
dpkg: error processing archive /var/cache/apt/archives/fonts-mathematica_18_all.deb (--unpack):
 trying to overwrite '/usr/share/mathematica-fonts/sha512-ttf', which is also in package mathematica-fonts 17

I assume that this is because fonts-mathematica doesn't correctly
declare Provides/Conflicts/Replaces dependencies in the control file.
