Trying to use version 77 I get a "wrong checksum" message:

Failed to download sources: module boost: Wrong sha256 checksum for 
boost_1_77_0.tar.bz2, expected 
"fc9f85fc030e233142908241af7a846e60630aa7388de9a5fafb1f3a26840854", was 
"4ffd1325229da00455ae95a68de976d053e46315628ffcd57a433238e74e7eab"

If I change the checksum in the download command to that shown above I 
get a "not  a .bz2 file" message.
