dnf output showing problem

I initially thought this was a repo problem that DNF wasn't responding to helpfully:

With yum:

----

---> Package texlive-kpathsea-lib.x86_64 3:2013-12.20140512_r33995.fc21 will be updated
--> Processing Dependency: texlive-kpathsea-lib = 3:2013-12.20140512_r33995.fc21 for package: 3:texlive-kpathsea-bin-svn30088.0-12.20140512_r33995.fc21.x86_64
---> Package texlive-kpathsea-lib.x86_64 3:2014-0.1.20140525_r34255.fc21 will be an update

...

               texlive-kpathsea-lib = 3:2014-0.1.20140525_r34255.fc21
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

----

But with DNF:

----

Running transaction check
Transaction check succeeded.
Running transaction test
Transaction test succeeded.
Running transaction
Transaction couldn't start (no root?)
Error: Could not run transaction.

----

(See full output in attachment)

But then I removed texlive-kpathsea-lib and dependencies, dnf still gives the same error. So, I did it with yum and everything was fine.

$ rpm -q dnf hawkey
dnf-0.5.2-2.fc21.noarch
hawkey-0.4.16-2.fc21.x86_64

Comment 1 Ales Kozumplik 2014-06-23 09:13:13 UTC
Matthew, it looks like you ran dnf under a regular user, without the noroot plugin (from dnf-core-plugins) installed. Is that the case?

Comment 2 Matthew Miller 2014-06-23 13:58:51 UTC
I'm pretty sure I ran it from my user account via sudo. 

In testing, the error sure does seem consistent with what would happen if I had forgotten the sudo. I don't *think* I'm that absent-minded, but I guess I'm getting older and that must be it.

Does "Transaction couldn't start (no root?)" mean "not running as root"? That didn't even occur to me, as it seems to be saying that the _transaction_ has no root, whatever that might be. (An unfortunate effect of "root" having multiple meanings.)

How about "Transaction couldn't start (required root privileges not available)" or something?

It would also be nice to have the error _before_ the packages are all downloaded.

Comment 3 Ales Kozumplik 2014-06-24 07:40:15 UTC
Improved the error message in 963bbe6, it is now going to say:

Failed to obtain the transaction lock (logged in as: akozumpl).

The 'noroot' plugin does exactly what you suggest, i.e. it stops DNF before any download happens and explains it nicely. 'dnf install dnf-plugins-core' should get you set.
