Arochester and Wiley One Thanks for the reply. Apologies my brain isn't working. I typed in that path /etc/apt/sources.list.d/additional-repositories.list with and without (Suite) and got no such command with Suite and /home/victoria without suite. Then I thought an etc directory isn't in home. So I went to the etc directory and into the additional repositories file. The only file in the [read only] list under /etc/apt/sources.list.d says:
deb https://dl.winehq,org/wine-builds
sudo apt-add-repository deb
which sounds familiar as what the 'How to' page told me to type.
Excuse this format. I didn't know how else to get the info here. Please tell me if and how I should report it, as the error message asks.
Also I was trying to put the info on a new usb to walk it over from the Linux machine which can't get on dial-up, and I have another question. There are files on the sandisk, do I need them on there, and would they interfere with an attempt to make a bootable disk with the usb drive? Thanks guys, my apologies for my incompetence.
