The instructions use the character O or is it 0, you cannot tell by looking at the screen or a printout. Another ambiguity is the command (s?): sudo wget http://wine.budgetdedicated.......... /etc/apt/sources.list.d/winehq.list Is this one long command continued on two lines, or is it two commands? I am not in the sudo list on my stock debian/etch installation, and do not wish to take three weeks to figure out how to add myself to the sudo list, so I used "su", and am now informed by apt-get that software can no longer be installed on my computer.
