I tried to install xtensor-blas onto Ubuntu and had the following error message. Please help!

[jzhang04]

CMake Error at CMakeLists.txt:47 (find_package): Could not find a configuration file for package "xtensor" that is compatible with requested version "0.21".

The following configuration files were considered but not accepted:

/usr/lib/cmake/xtensor/xtensorConfig.cmake, version: 0.10.11

-- Configuring incomplete, errors occurred!

You have an old version of xtensor installed on your system, you should upgrade to the latest. The package for Debian / Ubuntu is not maintained anymore, so you should probably remove it, and then install from source or with conda.

xtensor is now available again on Debian, https://tracker.debian.org/pkg/xtensor

Ubuntu will pick it up from there in due course, but in the meantime the Debian version might be installable on Ubuntu. Ubuntu packages have also been made for the FEniCS PPA, https://launchpad.net/~fenics-packages/+archive/ubuntu/fenics/+packages?field.name_filter=xtensor&field.status_filter=published&field.series_filter=
