Installation problems in a rhel9 container

I am trying to install kumomta on a rhel9 container, but running into the following issue:

❯ dnf install -y kumomta
Last metadata expiration check: 0:12:41 ago on Sun 05 Oct 2025 09:31:26 AM UTC.
Error: 
 Problem: cannot install the best candidate for the job
  - package kumomta-2025.05.06.055544_b29689af-1.rocky9.3.x86_64 from kumomta-stable does not have a compatible architecture
  - nothing provides ld-linux-x86-64.so.2()(64bit) needed by kumomta-2025.05.06.055544_b29689af-1.rocky9.3.x86_64 from kumomta-stable

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

We don’t currently provide pre-built arm binaries for that distribution. If you are willing to sponsor the project to cover the CI and ongoing maintenance costs, we can get that added.
