12.04 - uninstalling Atlas properly - Ask Ubuntu
https://askubuntu.com/questions/626351/uninstalling-atlas-properly
1 Answer 1 1 Answer 1 1 If you want to remove the ATLAS development packages, they are actually called libatlas-dev and libatlas-base-dev. However, there should be no need to uninstall these packages in order to use OpenBLAS: the update-alternatives mechanism will take care of things for you, automatically assigning higher priority to the OpenBLAS version of libblas when you install it e.g. with only the ATLAS development packages installed you should see $ update-alternatives --get-selections | grep libblas
libblas.so auto /usr/lib/atlas-base/atlas/libblas.so
libblas.so.3 auto /usr/lib/atlas-base/atlas/libblas.so.3 then installing OpenBLAS development packages using $ sudo apt-get install libopenblas-dev and checking again you should see $ update-alternatives --get-selections | grep libblas
libblas.so auto /usr/lib/openblas-base/libblas.so
libblas.so.3 auto /usr/lib/openblas-base/libblas.so.3 You should be able to swap between them using sudo update-alternatives --config libblas.so and following the on-screen instructions.
