Action items:
(1) Fix the EDSP protocol handler to not consider a non-downloadable
version as downloadable. Funny trickery.
(2) I see postgresql-client-16 is manually installed.
The answer here seems to be that when we go look at dependencies to
process:
postgresql-client as postgresql-client-16 | postgresql-client |
postgresqcl-client-17 | ...
instead of postgresql-client | postgresqcl-client-17 | ... |
postgresql-client-16
(i.e. keep the installed version as the primary choice, despite it being
obsolete; because it is manually installed)
However when comparing different dependencies, e.g. a.
Depends: postgresql-client (>= 17) and Depends: postgresql-client
which would expand to
postgresql-client | postgresqcl-client-17
postgresql-client-16 | postgresql-client | postgresqcl-client-17 | ..
that we process the dependency mentioning obsolete packages later.
This should approximately result in the correct behavior. A manually
installed package is preserved, even if obsolete, unless something else
needs a newer version (assuming we see "something else" early enough).
