This is the safest behaviour possible: you are *creating* a *new* zope3
instance called sandbox, it already exists on the filesystem but it does
not contain data. The default choice *has to be* to abort the
installation of the package *-sandbox, or you'll loose your old instance
without even being warned about this. Note that if you are using ZEO,
your instance won't contain any data and this doesn't mean that it's a
broken instance.

By the way, the only (standard) reason to have an old sandbox instance
is a broken installation of the package (or a manually created one).

I agree with you, I'll improve the error message before the abort.
I can do this even if the bug report is closed, but if you care you
could re-open it.

You could just `rm -fr /var/lib/zope3/instance/sandbox`.

It was zope3, see above.

No, if you are using ZEO your instance will not contain any data, just
configurations and maybe some source packages. Nothing broken, just no
data.

Thanks for your suggestion,
