A previously working dnf, on `dnf update`, produced the following traceback after listing upgraded packages: ''' Traceback (most recent call last): File "/usr/bin/dnf", line 36, in <module> main.user_main(sys.argv[1:], exit_code=True) File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 185, in user_main errcode = main(args) File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 84, in main return _main(base, args) File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 141, in _main ret = resolving(cli, base) File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 170, in resolving base.plugins.run_transaction() File "/usr/lib/python2.7/site-packages/dnf/plugin.py", line 82, in fn dnf.util.mapall(operator.methodcaller(method), self.plugins) File "/usr/lib/python2.7/site-packages/dnf/util.py", line 157, in mapall return list(map(fn, *seq)) File "/usr/lib/python2.7/site-packages/dnf-plugins/tracer.py", line 59, in transaction args = ["tracer", "-n"] + list(installed | erased) NameError: global name 'installed' is not defined ''' Versions of packages: ''' # rpm -qa | grep dnf dnf-plugins-extras-snapper-0.0.4-1.fc21.noarch dnf-plugins-extras-local-0.0.4-1.fc21.noarch dnf-plugins-extras-tracer-0.0.4-1.fc21.noarch dnf-plugins-extras-common-0.0.4-1.fc21.noarch dnf-plugins-extras-repoclosure-0.0.4-1.fc21.noarch dnf-plugins-extras-repomanage-0.0.4-1.fc21.noarch dnf-plugins-extras-0.0.4-1.fc21.noarch dnf-0.6.4-5.fc21.noarch dnf-plugins-extras-repograph-0.0.4-1.fc21.noarch dnf-plugins-core-0.1.5-2.fc21.noarch ''' On this system, it is 100% reproducable: ''' # dnf update Failed to synchronize cache for repo '_local' from 'file:///var/lib/dnf/plugins/local': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried, disabling.

I should add that `yum update` is working as expected.

Hello Robbie, thank you for the feedback. Unfortunately this issue isn't easy to solve. Clearly, there is a bug in dnf-plugins-extras-tracer plugin which causes this traceback. The bug was fixed long time ago, but it is not possible to build the new release for F21 because of dependency on new DNF. It is not that convenient, but `tracer` command works just fine - only the dnf plugin is bugged, so you still can run it manually. Also, the plugin is working on F22. My apologies
