Public bug reported: Using 20.04 updated on March 10, 2020. Freecad package 0.18.4+dfsg2-1ubuntu2.
Using Mesh workbench I was trying to create a mesh from solid using "Create mesh from shape..." menu. Using default settings empty mesh was created with no vertices nor edges (solid was not empty). Using python console I tried to `import MeshPart` and got an error message ...libnglib.so not found... Fix in 2 steps: 1) I had to install libnglib-6.2.1804. As mesh workbench is one of default workbenches of Freecad I suppose it should be a dependency for freecad package. 2) Package installs .so files into /usr/lib/x86_64-linux-gnu/netgen folder and the same error is still produced (even after ldconfig). After I added this folder path to x86_64-linux-gnu.conf and rerun ldconfig, `import MeshPart` works in Freecad's python console, and "Create mesh from shape..." produces usable mesh.
