dotnet-runtime has hard-coded dependency on libicu71

[Jeremy Bícha]

dotnet-runtime-6.0 and dotnet-runtime-7.0 have libicu71 listed in the Depends field of their debian/control files.

The purpose of the ${shlibs:Depends} is so that you don't need to have direct dependency on C libraries. For instance, they both have an automatic dependency on libc6 (>= 2.36) on Ubuntu 23.04 -- and libc6 (>= 2.34) on Ubuntu 22.04 LTS.

The shlibs systems also allows packages to be simply rebuilt for C soname library transitions like the current icu transition.

Please verify whether the direct dependency on libicu71 is needed or can be dropped.

Hi Jeremy!

When preparing the package to be submitted as New package, this was one of the things that changed due to the review process.

The reason was "dotnet is not linked against libicu, it dlopens it instead"

I'll review the package deeper to double check... thank you!

I am reopening this issue. It is a bug for these packages to depend on libicu71 which is no longer built from source. The dependency will need to be updated to libicu72.

Hi Jeremy!

Sorry for the misunderstanding. I closed the bug as "Won't Fix" because we cannot drop the dependency (as I understood that it was the debate here) and need to update libicu in every transition, in this case, to libicu72 as you pointed out right. You can see it in the latest upload:

https://launchpad.net/ubuntu/+source/dotnet7/7.0.103-0ubuntu1

Are you Ok if I close the bug again?

[Jeremy Bícha (jbicha)]

Yes, I closed the dotnet7 bug. Can you update dotnet6 too?
