| advanced modeling, e.g., exotic options and interest rate models.
|
| This package provides Python bindings to parts of the QuantLib library.

| dpkg: libquantlib-1.2: dependency problems, but removing anyway as you
| requested:
| quantlib-python depends on libquantlib0; however:
| Package libquantlib0 is not installed.
| Package libquantlib-1.2 which provides libquantlib0 is to be removed.
This is the problem. I think this needs what is called a 'hint'. The package
dependencies are correct -- but apt-get and dpkg simply hesitate to remove
the old libquantlib-1.2.
It is a little tricky as we 'used to use' libquantlib-1.2 to pretend it was
libquantlib0, and now we want to go back to the former.
Your initial report had it right but I read it wrong:
When upgrading to version 1.3-1 from 1.2-1, apt-get does not pull in the new
libquantlib0 package, which was being provided by the libquantlib-1.2
package.
I need to more strongly force libquantlib0 in, at the expense of
libquantlib-1.2.
I'll have a look at that.
Thanks for the detailed follow-up!
Dirk
