Description of problem:

I get unhandled exception when going back and forth after a file conflict. The exception is below. See steps to reproduce for details.

Traceback (most recent call first):
  File "/usr/lib/anaconda/users.py", line 243, in setUserPassword
    self.admin.setpassUser(user, password, True)

Version-Release number of selected component (if applicable):
anaconda 13.21.91

How reproducible:
Always

Steps to Reproduce:
1. Start a kickstart install with the Workstation variant (I guess anyone will do). Put the following packages section in the kickstart:

%packages
*
-@conflicts

2. The conflicts part is wrong. It should have been -@conflicts-<variant> instead. This leads to a file conflict in the transaction. 

file conflicts: file /usr/lib64/libcmpiCppImpl.so conflicts between attempted installs of libcmpiCppImpl0-2.0.1-5.el6.x86_64 and tog-pegasus-2:2.9.1-5.el6.x86_64

3. Anaconda catches the conflict and gives the user options to go back or exit. 
4. I selected to go back. Anaconda told me that I can't go back because file systems have already been partitioned. It offered me to exit the install or continue.
5. I selected to continue and shortly after I got this exception.
  
Actual results:
Exception.

Expected results:
Because I was not able to modify anything at the first place anaconda probably shouldn't have offered me to go back. 

OTOH because nothing changed I expected to see the same file conflict when doing back -> continue instead of a traceback.

Additional info:
Comment 1 Alexander Todorov 2011-01-27 16:03:04 UTC 
My last lines of anaconda.log are below. The exceprt starts after the file conflict and ends after I hit the traceback.

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.
Comment 4 David Cantrell 2011-02-02 18:39:29 UTC 
Is this still happening on current nightly trees?
Comment 5 Alexander Todorov 2011-02-03 08:23:51 UTC 
Same exception with latest nightly. See Job:50583.
Comment 6 David Cantrell 2011-02-05 01:04:11 UTC 
Using the 02-Feb nightly, I am unable to get the "TypeError: argument 1 must be Entity, not None" exception.  anaconda does throw up the warning for the libcmpiCppImpl0 conflicts with tog-pegasus, but I never see a traceback.

The conflict is a packaging error between those two components, so I'm going to reassign the component.  The conflict message from yum returned is:

    libcmpiCppImpl0 conflicts with tog-pegasus

The installation is performed via kickstart with the packages section looking like this:

    %packages
    *
    -@conflicts
    %end
Comment 7 Vitezslav Crhonek 2011-02-07 11:35:47 UTC 
libcmpiCppImpl0 must be conflicting with tog-pegasus - both contain non-compatible library with the same name and path.

There's a minor issue in tog-pegasus spec file - it doesn't have explicit "Conflicts: libcmpiCppImpl0". But libcmpiCppImpl0 states "Conflicts: tog-pegasus", so I think that's enough and it's not the problem.

Comment 8 Ondrej Vasik 2011-02-23 14:39:14 UTC 
Based on Comment #7 closing NOTABUG. Conflicts are necessary there and there was no change in tog-pegasus nor libcmpiCppImpl0 . So if you think this has to be solved, feel free to reopen and reassign to different place ( maybe comps groups are changed if the issue is new in 6.1? )
Comment 9 Alexander Todorov 2011-02-23 15:10:41 UTC 
Moving back to anaconda where it belongs.

Please see the steps to reproduce. This is still happening with the latest nightly.

After the file conflict the following thing happens:

3. Anaconda catches the conflict and gives the user options to go back or exit. 
4. I selected to go back. Anaconda told me that I can't go back because file
systems have already been partitioned. It offered me to exit the install or
continue.
5. I selected to continue and shortly after I got this exception.

Expected results:
Because I was not able to modify anything at the first place anaconda probably
shouldn't have offered me to go back and exit the installation directly.

OTOH because nothing changed I expected to see the same file conflict when
doing back -> continue instead of a traceback.

The original reported traceback no longer appears for me (TypeError: argument 1 must be Entity, not None).  I can see removing the 'Back' option for kickstart installs as you can't really do anything at that point with changing your package selection.  Those windows also pop up for people doing interactive installs, and since depsolving happens when you leave the package selection screen, we can still go back at that point.

(Changing the title on this bug too.)

With anaconda-13.21.103-1.el6.x86_64 I no longer see the "TypeError: argument 1 must be Entity, not None" traceback. However I still see the Back button while comment #11 implies that it will be removed.

The Back button in the dialog that pops up telling you the depsolving step cannot finish lacks the Back button now, what back button are you referring to?  Also, how are you trying to verify this bug now?  What steps are you performing exactly?
Comment 17 Alexander Todorov 2011-03-09 16:07:20 UTC 
I'm using the steps to reproduce from comment #0, i.e. install with this ks.cfg:

%packages --ignoremissing
@Base
*
-@conflicts
%end

See attached screenshots. Btw I still got the TypeError: argument 1
> must be Entity, not None traceback.

This is the first time Anaconda tells me about the file conflict. The window has a Back button.

After I press Back I see this window. I press Continue.
