Hello Villani,

just before the error at the end you can see a couple of lines:

--8<--
[...]
CST error 43:
  -> Thorn 'TwoPunctures_KerrProca' requires the capability 'GSL'.
     Please add a thorn that provides 'GSL' to your ThornList or remove 'TwoPunctures_KerrProca' from it !

CST error 44:
  -> Thorn 'WatchDog' requires the capability 'PTHREADS'.
     Please add a thorn that provides 'PTHREADS' to your ThornList or remove 'WatchDog' from it !
--8<--

and at the beginning of that list of errors you can see the following:

--8<--
------------------------------------------------------
Warnings were generated during execution of the CST
------------------------------------------------------

CST error in /home/mattia/Cactus/lib/sbin/CST (at 376)
  -> Missing thorn ExternalLibraries/BLAS

CST error in /home/mattia/Cactus/lib/sbin/CST (at 376)
  -> Missing thorn ExternalLibraries/FFTW3

CST error in /home/mattia/Cactus/lib/sbin/CST (at 376)
  -> Missing thorn ExternalLibraries/GSL
--8<--
indicating that some modules (thorns) could not be downloaded and are missing.

Those missing are downloaded using subversion (using the svn command) and possibly you are missing it.

Steve already asked this, but can you double check that you ran the command (all in one line):

sudo apt-get install -y libjpeg-turbo?-dev gcc git liblapack-dev make subversion g++ libpapi-dev libhwloc-dev libopenmpi-dev libhdf5-openmpi-dev libssl-dev numactl gfortran libhdf5-dev libfftw3-dev patch rsync libgsl-dev pkg-config

and that 

svn --version

works?

If that works, can you please provide the log files generated by:

cd $HOME
./GetComponents --update ./einsteintoolkit.th &>GetComponents.log

and

svn info https://github.com/einsteintoolkit/ExternalLibraries-GSL.git &>svn.log

ie the two files GetComponents.log and svn.log .

Yours,
Roland
