Hi,
currently I am trying to compose a tree for CentOS Atomic, on Fedora. But it seems to fail. For this I posted a question on the forum [1]. The error shown is: Writing '/var/tmp/rpm-ostree.OaWsmG/rootfs.tmp/usr/share/rpm-ostree/treefile.json' /var/tmp/rpm-ostree.OaWsmG/rootfs.tmp/usr/share/rpm: No such file or directory error: Unable to find package 'yum' specified in remove-files-from It is a clean install of Fedora 23... and I use the command: git clone https://github.com/CentOS/sig-atomic-buildscripts \ -b downstream \ --depth 1 \ centos-atomic rpm-ostree compose tree \ --repo=/srv/repo \ ./centos-atomic/centos-atomic-host.json The full output is at [2]. Doing the same for Fedora Atomic is succesful. regards, Gerard [1] http://ask.projectatomic.io/en/question/3808/centos-atomic-compose-fails-with-unable-to-find-package-yum-specified-in-remove-files-from/ [2] https://gitlab.com/gbraad/byo-atomic-centos/builds/2204362 -- Gerard Braad | http://gbraad.nl [ Doing Open Source Matters ]
