Description of problem: This was originally reported as bug #444979: Suppose one completes (partially or totally) the first phase of preupgrade - until reboot. Than it changes mind and don't want to perform the upgrade. Could you please explain how to revert system in the old *clean* state (delete all packages, images and grub entries that preupgrade has created, freeing disk space) ? Actual results: There is no apparent way of regaining the clean system state if upgrade via preupgrade is interrupted. Expected results: Please provide a way (software, documentation) for regaining a clean system state in upgrade is interrupted. Regards, Răzvan
1. you have to remove the entry from your /etc/grub.conf manually - it should be the first entry 2. go to /var/cache/yum/preupgrade and remove all the files here. that should be it.
preupgrade modifies data in ~3 places: /var/cache/yum/preupgrade* /boot/upgrade /etc/grub.conf If you want to clean up manually, you can do: grubby --remove-kernel=/boot/upgrade/vmlinuz rm -rf /var/cache/yum/preupgrade* /boot/upgrade In preupgrade-0.9.8 and later, you can restart preupgrade and answer "No" when it asks if you wish to continue your incomplete upgrade. That will clear out the caches in /var/cache/yum/preupgrade-* and /boot/upgrade. You may still need to run grubby (or edit /etc/grub.conf by hand).
Hello, This is absolutely *great news* , but, IMHO, the following action is needed: - please add a switch to preupgrade, for automatic cleaning of interrupted upgrades (something like "preupgrade --clean") - please document clearly this options in some *visible* place, say preupgrade's man page and/or online manual. Regards, Răzvan
just encountered it with F17->F18beta. Cleaned the system using the above methods, it still not cleaned enough - it does not prompt me to again get the files for F18beta. Re-opening as a RFE.
Preupgrade is obsoleted in favor of fedup. It can't possibly work to upgrade to F18 because the F18 installer doesn't support preupgrade - or any kind of upgrade at all. This is handled by fedup now - see bug 874495. As for cleanup - "fedup-cli --clean" should remove everything that fedup has changed: delete downloaded files, remove symlinks, revert bootloader changes, etc. If fedup-cli --clean doesn't clean everything, please open a new bug against fedup.
