Description Björn Tantau 2024-07-17 13:31:57 UTC

Very often for me a `zypper dup` operation fails for me because the dependencies of some packages still require an obsolete package.

````
Problem: 1: the installed libcholmod3-3.0.12-150100.9.2.3.x86_64 requires 'libopenblas_pthreads.so.0()(64bit)', but this requirement cannot be provided
deleted providers: libopenblas_pthreads0-0.3.25-150500.4.5.2.x86_64

 Solution 1: Following actions will be done:
  deinstallation of hipsolver-2.1.1.60101-sles154.90.x86_64
  deinstallation of hipsolver-devel-2.1.1.60101-sles154.90.x86_64
  deinstallation of rocm-hip-libraries-6.1.1.60101-sles154.90.x86_64
  deinstallation of rocm-hip-sdk-6.1.1.60101-sles154.90.x86_64
  deinstallation of rocm-ml-libraries-6.1.1.60101-sles154.90.x86_64
  deinstallation of rocm-ml-sdk-6.1.1.60101-sles154.90.x86_64
  deinstallation of rocm-6.1.1.60101-sles154.90.x86_64
 Solution 2: keep obsolete libopenblas_pthreads0-0.3.25-150500.4.5.2.x86_64
 Solution 3: break libcholmod3-3.0.12-150100.9.2.3.x86_64 by ignoring some of its dependencies

It would be great if we had an option to always take the "keep obsolete" solution. Especially for automated updates or for cases where this applies to lots of packages (like in #1214303). I think keeping a few obsolete packages is preferable to not updating everything else or breaking or removing something.
