jsMath problem in SAGE on Ubuntu

November 30th, 2008 | Categories: sage interactions | Tags:

I have just installed SAGE 3.2 on my Ubuntu 8.10 machine and received the following error message.

It looks like jsMath failed to set up properly (error code -7). I will try to keep going, but it could get ugly.

I discovered a forum thread that suggested that installing jsmath-fonts would fix the problem

apt-get install jsmath-fonts

but, unfortunately, it didn’t. I found that I also had to install ttf-jsmath

apt-get install ttf-jsmath

A quick restart of firefox later and SAGE looked very pretty indeed!

    The ttf-jsmath package doesn’t exist on earlier versions of Ubuntu. On 8.04, at least, you can install the 8.10 package, by downloading it and

    sudo dpkg -i ttf-jsmath*.deb
