  [Failed to resolve the transaction:
Package "pkgconf-pkg-config-2.3.0-1.fc42.aarch64" is already installed.
Problem: cannot install both gcc-15.0.0-0.2.fc42.aarch64 from https_dmalcolm_fedorapeople_org_gcc_gcc_15_mass_prebuild_arch and gcc-14.2.1-6.fc42.aarch64 from fedora
  - package libtool-2.5.4-1.fc42.aarch64 from fedora requires gcc(major) = 14, but none of the providers can be installed
  - cannot install the best candidate for the job
  - conflicting requests
You can try to add to command line:
  --no-best to not limit the transaction to the best candidates]: [Package `libtool-2.5.4-1.fc42.aarch64` has an unmet dependency on `gcc(major) = 14`.]
