Please apply the following two upstream patches to the anaconda package for Fedora 23: Skip OEMDRV if interactive DD is requested (#1254270) https://github.com/rhinstaller/anaconda/commit/3831bdf1142d7954ab19a6b43b3009a065cc6b3f.patch Fix 'cat: /tmp/dd_disk: No such file or directory' (#1251394) https://github.com/rhinstaller/anaconda/commit/2b38d463bfaf36fb393e87e277c956dee2320b5d.patch These two patches apply cleanly onto Fedora 23 (in order), and they have already been applied for Fedora 24 and RHEL 7. They are needed in order to compose a Fedora 23 image using Pungi, which is currently failing with this error.
Why are these causing problems with pungi? These are related to driver update disks and should have no effect on pungi.
You're right, I was experiencing an issue completely unrelated to pungi and there was some miscommunication in working with my colleagues. Sorry for the noise.
