I get the bug described here when trying to upgrade to Fedora 20 from Fedora 17.
The symptom is that the first stage of upgrade (before rebooting) works successfully, but when you reboot to complete the upgrade, the second stage begins but almost immediately aborts and reboots back to your previous Fedora system.
Guess I'm running fedup 0.7 (see terminal output)
[root@localhost mylaptop]# yum install fedup Loaded plugins: langpacks, presto, refresh-packagekit Package fedup-0.7.3-5.fc17.noarch already installed and latest version Nothing to do
There is a mention about getting fedup 0.8 from updates repository but that's in my repolist:
[root@localhost mylaptop]# yum repolist Loaded plugins: langpacks, presto, refresh-packagekit repo id repo name status adobe-linux-x86_64 Adobe Systems Incorporated 2 fedora/17/x86_64 Fedora 17 - x86_64 27,033 updates/17/x86_64 Fedora 17 - x86_64 - Updates 13,163 repolist: 40,198
The solution described is to update fedup to 0.8 but as you can see in the output it won't because 0.7 is installed and latest version. What am I to do next?
Got the fedup package from http://kojipkgs.fedoraproject.org//packages/fedup/0.8.0/3.fc18/noarch/fedup-0.8.0-3.fc18.noarch.rpm
After installing (double clicking the file); as root copied the files I've already downloaded using fedup 0.7
cp -R /var/lib/fedora-upgrade /var/lib/system-upgrade cp -R /var/tmp/fedora-upgrade /var/tmp/system-upgrade
Running fedup again as root:
fedup --network 20 --nogpgcheck
After that it will boot through the update upgrade and boots into .... Fedora 17 :(
Can reboot again and have the upgrade option again that will boot into 17 again minus a working wifi.
