Answer 1

The following worked for me.

1. Download the version of asdf.lisp you want from https://common-lisp.net/project/asdf/asdf.html. In my case, I copied mine from my system's installed copy located at /usr/share/common-lisp/source

2. Put the new copy in the ~/quicklisp directory, or whichever directory your quicklisp is located, overwriting the old asdf.lisp in that directory.

3. Delete the ~/quicklisp/cache directory.

4. Restart your lisp. It will take a while to repopulate the ~/quicklisp/cache directory so be patient.
