--- Comment #8 from mat...@dnet.it --- Hi Jack, I dont know if the guys will be able to backport the fix, and how long it is going to take. However, you can build a custom version for yourself very easily in the meantime. Here some instructions on how to go about it (run these in the terminal): #make a temporary directory mkdir /tmp/cantor cd /tmp/cantor #download the source of your currently installed cantor package sudo apt-get install debian-keyring sudo apt-get source cantor #the above will create a subdirectory called "cantor-version-number-something" #in there you will find the directory "src" (i cant test right now, so you might have to look for it) #find and edit the file "src/backends/sage/sagesession.cpp" according to the submitted patch #which you can find here: https://quickgit.kde.org/?p=cantor.git&a=commitdiff&h=5d185d21431a989055ab4a1501584dbb3ea17842&hp=ad75e06d3b4317ab45e1b84419b9abb8e33ad6fa #this patch is very simple: you only have to ad "+(|Math)" right after "Sage" on the right line #the "right line" is 194 for the latest cantor, but it might be some lines up or down in your version #now rebuild the package sudo apt-get install dpkg-dev sudo apt-get install build-dep cantor cd "cantor-version-something" dpkg-buildpackage -b -us -uc cd .. #you should now have some debian packages #install the sage backend with sudo dpkg -i cantor-backend-sage*.deb Once again, this is just the temporary workaround that I used until the change will show up in the official Ubuntu repositories. Good luck! Matteo -- You are receiving this mail because: You are watching all bug changes.
