I got the following error messages when I try to re-load software & updates:

E:The repository 'http://ppa.launchpad.net/mc3man/xerus-media/ubuntu zesty Release' does not have a Release file.
W:Updating from such a repository can't be done securely, and is therefore disabled by default.
W:See apt-secure(8) manpage for repository creation and user configuration details.
E:The repository 'http://ppa.launchpad.net/shutter/ppa/ubuntu zesty Release' does not have a Release file.

I tried solution at Xenial repository does not have a Release file but it does not work for me.

You get that error when the line is incorrectly typed or the server does not answer in an expected way. In your case, I'm almost sure you typed the address incorrectly.

Look in /etc/apt and inspect either the big sources.list or files in sources.list.d. Note these have a SLASH after "ubuntu/". All of mine do, eg:

deb http://us.archive.ubuntu.com/ubuntu/ artful main restricted
deb-src http://us.archive.ubuntu.com/ubuntu/ artful restricted multiverse main universe

Also, be aware that ppa servers come and go rapidly.
