After I have upgrade from ubuntu 16.10 to 17.04, each time I use software updater I am asked to do partial apgrade
when I try partial upgrade I get the following error:
upgrade An upgrade from 'Zesty' to 'zesty' is not supported with this tool.

I suppose your /etc/apt/sources.list does not only use 'zesty'
