Dear Bruce, First of all, thank you for your response. I did not update Mint, I installed a fresh version (formated the drive, installed a new version, remounted my data partitions, including the home folder, and reinstalled all the packages from the repositories), sorry if I did not make it clear enough in the first email. The demeter folder in the home folder was carried over from the old linux version, but I downloaded the newest version from the github repo. I would think this is basically equal to starting with a blank OS. Anyway, I did try the ./Build touch_wrapper command without any success (same tests failed if I remember correctly). As you asked me about athena crashing, for the purpose of testing it, I went on and installed athena despite the errors in the ./Build test command (without downloading the new version from the github repo). This is the terminal output: ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Attribute (bkg_nc0) does not pass the type constraint because: Validation failed for 'LaxNum' with value 0,34568900723742 at accessor Demeter::Data::bkg_nc0 (defined at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/Data.pm line 310) line 4 Demeter::Data::bkg_nc0('Demeter::Data=HASH(0xcf3fd70)', '0,34568900723742') called at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/Data/Mu.pm line 323 Demeter::Data::Mu::normalize('Demeter::Data=HASH(0xcf3fd70)') called at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/Data.pm line 717 Demeter::Data::_update('Demeter::Data=HASH(0xcf3fd70)', 'fft') called at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/Data/Plot.pm line 24 Demeter::Data::Plot::plot('Demeter::Data=HASH(0xcf3fd70)', 'E') called at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/UI/Athena.pm line 2177 Demeter::UI::Athena::plot('Demeter::UI::Athena=HASH(0x1a65618)', '', '', 'E', 'single') called at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/UI/Athena.pm line 2376 Demeter::UI::Athena::quadplot('Demeter::UI::Athena=HASH(0x1a65618)', 'Demeter::Data=HASH(0xcf3fd70)') called at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/UI/Athena/IO.pm line 238 Demeter::UI::Athena::IO::Import_plot('Demeter::UI::Athena=HASH(0x1a65618)', 'Demeter::Data=HASH(0xcf3fd70)') called at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/UI/Athena/IO.pm line 813 Demeter::UI::Athena::IO::_prj('Demeter::UI::Athena=HASH(0x1a65618)', '/home/stevan/Documents/.../athenaprojectname.prj', '/home/stevan/Documents/.../athenaprojectname.prj', 1, '') called at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/UI/Athena/IO.pm line 164 Demeter::UI::Athena::IO::Import('Demeter::UI::Athena=HASH(0x1a65618)') called at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/UI/Athena.pm line 857 Demeter::UI::Athena::OnMenuClick('Wx::Frame=HASH(0x19a2980)', 'Wx::CommandEvent=SCALAR(0xcf2b6d0)', 'Demeter::UI::Athena=HASH(0x1a65618)') called at /home/stevan/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/UI/Athena.pm line 780 Demeter::UI::Athena::__ANON__('Wx::Frame=HASH(0x19a2980)', 'Wx::CommandEvent=SCALAR(0xcf2b6d0)') called at /home/stevan/perl5/bin/dathena line 39 eval {...} at /home/stevan/perl5/bin/dathena line 39 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- After removing demeter and perl5 folders from the home directory, downloading the latest packages from the github repo and building from scratch, all test were successful in the ./Build test step.
