Description of problem: While trying to install a latest rawhide ISO image, anaconda fails to start with error message ModuleNotFoundError: No module named 'pyanaconda.threads' $ anaconda Starting installer, one moment... Traceback (most recent call last): File "/usr/sbin/anaconda", line 282, in <module> from pyanaconda import startup_utils File "/usr/lib64/python3.6/site-packages/pyanaconda/startup_utils.py", line 40, in <module> from pyanaconda import kickstart File "/usr/lib64/python3.6/site-packages/pyanaconda/kickstart.py", line 22, in <module> from pyanaconda.threads import threadMgr ModuleNotFoundError: No module named 'pyanaconda.threads' Version-Release number of selected component (if applicable): anaconda-27.14-1.fc27 How reproducible: * Garb a latest rawhide iso image e.g. https://kojipkgs.fedoraproject.org/compose/rawhide/Fedora-Rawhide-20170621.n.0/compose/Workstation/x86_64/iso/Fedora-Workstation-Live-x86_64-Rawhide-20170621.n.0.iso * Boot the iso and start anaconda installation * Fails while loading anaconda Noticed this behavior on both x86_64 and ppc64(le). Haven't checked other arches.
This should be fixed once anaconda-27.15-1 hits the composes.
Rawhide nightly compose from 20170622.n.0 seems to have anaconda-27.15-1 . Anaconda installer starts perfectly and was able to install successfully iso from 20170622.n.0 .
I'm getting this same issue on recent Fedora 26 rebuilds with anaconda-26.21.12-1.fc26.x86_64
On Fedora 26 it looks like the trouble package update was for python3-blivet-2.1.11-1.fc26.noarch which gives the following error when trying to run liveinst: Traceback (most recent call last): File "/sbin/anaconda", line 577, in <module> blivet.enable_installer_mode() File "/usr/lib/python3.6/site-packages/blivet/__init__.py", line 127, in enable_installer_mode from pyanaconda.anaconda_logging import program_log_lock ModuleNotFoundError: No module named 'pyanaconda.anaconda_logging'
Downgrading python3-blivet on my troubled livemedia fixes it.
Nevermind, I see this new bug report (https://bugzilla.redhat.com/show_bug.cgi?id=1497677) and they already have an updated package in updates-testing.
