That's fairly old. In practice, I recommend upgrading to the latest stable
when having trouble such as yours.

Problem: upgrading cleanly from asdf 2 is possible, but can be tricky.
The latest 3.1 has a script to install itself on top of an existing
implementation;
but it's not part of an official stable release yet.

Great.

I believe so, though my understanding is the debian package CL
libraries are not that well maintained anymore. These days, all the
cool kids use quicklisp. Now, if you could write an automated
quicklisp to debian packager...

Back in the bad old days, c-l-c was trying to have a system cache.
This turned out to be a configuration and security nightmare.

These days, people are happy just using a per-user cache;
on single-user machines this is not a problem;
and on multi-user machines, that's probably better for security
(not to say about robustness against race conditions).

A file is compiled the first time only. Subsequent times,
the cache will be used, as long as the file is up-to-date.

In the past, there have been bugs with respect to following symlinks,
handling directory pathnames without a trailing slash, etc., etc.

I would recommend upgrading ASDF over trying to debug an old one.
