    2020-03-25T14:11:10+01:00 [2766] [error] Caught exception: There is either a configuration problem with TrueType or a problem reading font file "/usr/share/tuleap/src/embedded_vendor/jpgraph/fonts/DejaVuSans.ttf" Make sure file exists and is in a readable place for the HTTP process. (If 'basedir' restriction is enabled in PHP then the font file must be located in the document root.). It might also be a wrongly installed FreeType library. Try upgrading to at least FreeType 2.1.13 and recompile GD with the correct setup so it can find the new FT library.:
