good morning,

i tried to update all packages from AIX Linux toolbox on local repository. But i got this error messages:

Error:
 Problem: package python3-setuptools-rust-1.11.1-1.noarch requires python3.12-setuptools-rust = 1.11.1-1, but none of the providers can be installed
  - cannot install the best update candidate for package python3-setuptools-rust-0.12.1-2.noarch
  - nothing provides libunwind.a(libunwind.so.1) needed by python3.12-setuptools-rust-1.11.1-1.noarch
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

Before the update all repositories are synced with IBM.
