Hi, I have fedora 18 on my PC.
Here my PC specs:

-AMD Processor
-Ram 4Gb
-Motherboard Gigabyte
-OS Fedora 18 x64

My questions is.. Is it possible upgrade my F18 to F20 via fedup on yum?
and if it's possible.. Is it official now or I should stay tuned for upgrade via yum?

My main concern is my data :)
Thanks in advance !

If your main concern is data, then I would get the network boot media (presuming your internet connection is fast enough) and install F20 that way; as more then likely every piece of software you've already got installed will get updated anyway. Obviously if your internet is too slow then don't get the network boot iso, but rather a live DVD of your choice. I feel the pain of not having much internet, as I used to have 512mb. If you need too, you could get the DVDs from (F20 is not on there yet, just give them a week or so).

i %99 sure that you can't upgrade from 18 to 20 , the upgrades are from version to version 18 to 19 , 19 to 20 .

so you need download fedora 20 and later install, is the best way ;)

good luck !

You're right, I think I will do a backup of my data and then I will install F20 via DVD, of course I will burn the ISO before ;) Thanks for your comments !

Before making any unpdate or install it is ever a goog idea make a backup, I made a update from Fedora 17 to Fedora 19, so update from 18 to 20 it is posible.

It seems that it is possible: See

what this link points to as important is to make sure you take this into account:

The short answer is:

fedup --network 20 --nogpgcheck

should work perfectly (lol that this has not been my experience going 19->20)

Thanks, but I'm not sure to upgrade via fedup, but I will save my data and then I will install F20 via DVD installer ;)

That's really not necessary. Some prefer it but it's one of the things I love about Linux. Backing up is not a bad idea but once you've done that just hit ctrl+alt+F2 and type the commands. It may seem daunting to begin with but honestly the command line is extraordinarily powerful once you start getting used to it.

yap, i think this will work. i will test it... i've been always using a upgrade over yum or fedup, sometimes it needs a knowledge, specially if there was some major changes.

in Fedora 18, you need to update fedup from 0.7 to 0.8 first, yum uodate fedup fedora-release, or you may get an error.

good to know! for me it wasnt problem, because i always do a update before upgrade :)

When you used fedup --network 20 ....etc was your pc in run level 5, or in single user mode?

Upgrades are time consuming and there is no guarantee that they will work. I my opinion it is best to save important data and do a fresh install. The last fresh install I did (Fedora 20) took about 15 minutes.

Yes, I had F18 and I prefered to install F20 via Live DVD, before I save my data in NTFS partition and work fine now !

For upgrades to Fedora 18 and later, the recommended upgrade method is the FedUp tool.

Although upgrades with yum do work, they are not explicitly tested as part of the release process by the Fedora QA and are not documented in the Fedora installation guide.

When upgrading with yum you don't get any help from FedUp or Anaconda.
