It appears there is no direct variable assignment available. You have to use .set() and .get_value() which makes this really awkward. When using .set() it needs a priority, with RUNTIME having the highest precedence. Otherwise the new config setting won't take effect. Managed to get it to download metadata and show the NEVRA of the packages selected on the cmdline. It seems to run the transaction -- goal.resolve() takes a long time and the CPU is busy. But I cannot figure out how to do anything with the transaction. It returns a memory leak error and I cannot iterate the result. (Pdb) trx.get_transaction_packages() <Swig Object of type 'std::vector< libdnf::base::TransactionPackage,std::allocator< libdnf::base::TransactionPackage > > *' at 0x7f5b257d83c0> swig/python detected a memory leak of type 'std::vector< libdnf::base::TransactionPackage,std::allocator< libdnf::base::TransactionPackage > > *', no destructor found.
Ends up you need to call sack.create_repos_from_reposdir() to load the repo files copied into the temporary reposdir. And find needed to be rewritten to use the new API. Previous issues were due to missing swig bindings for python. Fixed in commit e6631ceb50ba69b475f4edc1e6be7b416544d430 from the dnf5 repo.
