Comment 9 for bug 2061319

I can confirm that xgridfit from focal-proposed has fixed the bug for me.

Test done:

install xgridfit and try to execute "xgridfit --help", "xgfconfig --help" and "ttx2xgf --help" and confirmed that they still fail.

Added focal-proposed to apt sources.
install xgridfit from focal-proposed.

execute "xgridfit --help", "xgfconfig --help" and "ttx2xgf --help" and confirmed that they all display the help message.

Package tested:

$ apt-cache policy xgridfit
