RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem
======================

preupg fails if stdin is not terminal:

    # preupg <<<y
    The Preupgrade Assistant is a diagnostics tool 
    and does not perform the actual upgrade.
    Make sure you back up your system and all of your data now,
    before using the Upgrade Tool to avoid potential data loss.
    Do you want to continue? y/n

    preupg: error: list index out of range
    #


Version-Release number of selected component
============================================

preupgrade-assistant-2.0.3-8.el6


How reproducible
================

Always if stdin fed from pipe


Steps to Reproduce
==================

    preupg <<<y


Actual results
==============

Error from content and eventually preupg taken down.


Expected results
================

No failure.


Additional info
===============

Possibly there is also some problem with the content, but OTOH preupg
should be able to prevent this (by closing stdin for contents...if
it's doable...?)

Also note the Usage: message---this is probably also not intentional.

Great bug. I will look on it.
Comment 5 Petr Hracek 2015-11-03 11:42:38 UTC 
For now I have fixed the issue by upstream commit https://github.com/phracek/preupgrade-assistant/commit/16be28741f77a45082d58fff9cd84fc3601afa7c

It doesn't finish with traceback and output looks like:

[root@rhel6 ~]# preupg --skip-common --debug  <<<y
