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 Tomas Tomecek 2013-07-02 14:23:11 UTC 
If yum cache at /var/cache/yum contains packages from multiple repos and there are duplicate rpms, build fails:

cp: will not overwrite just-created `repo/file-devel-5.04-15.el6.x86_64.rpm' with `/var/cache/yum/build-released/packages/file-devel-5.04-15.el6.x86_64.rpm'

Unfortunately this is happening quite often when we try to run static analysis scans on this package in mock chroot environment. We have to modify SRPM to scan it properly.

Slight modification was working for me fine (cp won't mind overwrite now):

Comment 4 Tomas Tomecek 2013-07-04 12:05:36 UTC 
Well, your fix is much more secure than mine. I verified it and it works very well. Thank you.
Comment 5 bfan 2013-07-30 05:55:28 UTC 
Hello Tomas, 
May I know you verified this bug with developer's patch or a new build package?

If only using patch, could you please help us to verify it with libguestfs-1.20.9-7.el6, thanks

I've just rebuilt it (with multiple yum repos enabled) and it passed.

This was the problematic part (no errors or even warnings anymore):

+ mkdir repo
+ find /var/cache/yum -type f -name '*.rpm' -print0
+ xargs -0 -n 1 cp -t repo 

So, I can verify that the bug is fixed.

Hello Tomas, 
As I see, this bug occurred when build the libguestfs package, I spent time to read libguestfs.spec and try to build the package,but failed.  It would be easier for you to build the libguestfs package than me, so could you help to reproduce and verify this bug with the latest version of libguestfs: libguestfs-1.20.11-2.el6 ?

Thanks & Best regards

Hello Tomas,
Thanks for your help. Also, I checked libguestfs.spec of libguestfs-1.20.11-2.el6, it have been changed like Comment 3. So, this bug is fixed.
