Thanks for the report Jiri.

This is possibly the kernel package specific, will take a look.

$ dnf list gnutls*
works as expected

This is a missing capability of the hawkey library, it won't parse globbed version. Phillip, you are seeing a different bug, would you please open a new bugzilla with your comment plus the dnf version you see this? Thanks!

Also, libsolv doesn't really downgrades of other packages. This is not a problem for zypper, as zypper will present solutions to the user if it runs into problems. Dnf just prints the problems end exits.

You can kind of work around this by setting HY_ALLOW_UNINSTALL if dnf is in "downgrade" mode, in that case libsolv is free to downgrade/uninstall packages that are in the way.

Fixed by a series of patches to hawkey and the dnf commit 51c9d08. Will be included with the next DNF release in F20.
