Trying to install Flash Player on Ubuntu

[boblfixit6]

I am trying to download Adobe flash to my new hard drive. The OS is UBUNTU. the suggested app is APT for Debian/UBUNTU. When i hit download, it starts, but then an error message pops up - Unknown channel 'bionic partner'   The channel 'bionic partner' is not known.

Moving this discussion to the Installing Flash Player forum.

Looks like the partner repository hasn't been added to your system.  See the Ubuntu documentation at https://help.ubuntu.com/stable/ubuntu-help/net-install-flash.html.en
