AIMS-desktop is developed at the African Institute for Mathematical Sciences - South Africa (http://www.aims.ac.za), a centre for education and research in Cape Town, South Africa, and the first centre in the AIMS network.

The AIMS desktop PPAs listed here are deprecated. AIMS desktop is moving from an Ubuntu derivative to a Debian derivative. We expect to launch shortly after Debian Stretch is becomes the next stable release in 2017.

We hope to continue updating the Sagemath PPA for Ubuntu on a best-effort basis, but Sage is available in Debian stretch (December 2016), so will be in Ubuntu from 17.04, or you can (manually) install the binaries from http://www.sagemath.org/download.html
