Upgrading Fedora from Version Spherical Cow version 18 to the latest Schrödinger’s Cat version 19.
The official Fedora documentation is a good friend.
All following steps as root or with sudo;)
1. Backup your system
2. Do the upgrade
1 2 | yum install fedora-upgrade
fedora-upgrade |
You will be asked at the end for a reboot
After reboot update yum to latest version available in your Fedora version
1 | yum update yum |
3. Clean up
1 | yum clean all |
Enjoy Schrodinger’s Cat
After installing of new fedora 18 version at work, I was looking unsuccessfully for rc.local. TO modify some typical work routines.
From Fedora documentation
3.2.4. rc.local no longer packaged
1 2 | touch /etc/rc.d/rc.local chmod +x /etc/rc.d/rc.local |
I forgot to set the correct time zone as I installed my new Fedora 18 system.
So this can be also done after the completed installation:
1 | ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime |
The localtime symlink will show to the proper timezone file.
After some days of my vacation, my Fedora workstation was not able to boot. I stuck in the grub rescue shell, something was wrong with my MBR-recoord. There was a wrong UUID.
As I tried to update grub (command update-grub) – I stuck again – command not found! This is a Debian/Ubuntu specific command and is not available here.
This is a update-grub in Fedora way:
1 | grub2-mkconfig -o /boot/grub2/grub.cfg |
And finally the MBR installation:
1 | grub2-install --recheck --no-floppy /dev/sda |
I started to install update (yum update) on my fedora system and by mistake abort the operation with CTRL+C, I tried to start the update process again (yum update) but I get only this:
Loaded plugins: langpacks, presto, refresh-packagekit
[Errno 14] HTTP Error 404 – Not Found
yum clean all |
was the solution for this problem
