Sorry, I copied the above instructions and didn't proofread them for
mistakes.  The third step should be:

    (setq package-check-signature 'allow-unsigned)

'C-h v' will tell you the value of a variable.  You can also use 'M-x
customize-option RET' which is usually the prefered way of setting
user-options.

> PS. FYI I was trying to get a bit of experience with the latest AucTeX because I have volunteered to help Wim Treese, the new maintainer of Aquamacs, prepare the documentation for a new version which among other things will allow it to follow Emacs versions better. I will need to learn elisp for that job, but a little help setting package-check-signature back to its default would be appreciated in case I have left it in a dangerous state.

If it is set to nil, that just means that signatures are not checked.
Since you used setq above, the value will reset to the default the
next time you restart Emacs.

Best of luck with your forays into Emacs Lisp!
