dnf update breakage

[bondhugula]

On my CentOS Linux release 7.6.1810 (Core), doing a dnf update yields:

Traceback (most recent call last):
File "/bin/dnf", line 58, in <module>
main.user_main(sys.argv[1:], exit_code=True)
File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 179, in user_main
errcode = main(args)
File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 64, in main

File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 99, in _main
return cli_run(cli, base)

tid = self._run_transaction(cb=cb)
File "/usr/lib/python2.7/site-packages/dnf/base.py", line 1021, in _run_transaction
self._verify_transaction(cb.verify_tsi_package)

bool(return_code)
File "/usr/lib64/python2.7/site-packages/libdnf/transaction.py", line 758, in endTransaction
return _transaction.Swdb_endTransaction(self, dtEnd, rpmdbVersionEnd, state)
RuntimeError: TransactionItem state is not set: kernel-devel-3.10.0-514.el7.x86_64

Doing a 'dnf clean packages' and rerunning this yields the same result.

I believe dnf is only a "tech preview" in RHEL 7 so from that POV, when it breaks you get to keep all the pieces. In 7, yum is the preferred package manager.
