You can upgrade from Fedora 18 to Fedora 20

Posted: December 20, 2013 in geek stuff, work

It took me a while to find this… so I wanted to post it very clearly. You can upgrade a Fedora 18 machine directly to Fedora 20. Thanks to Christine Caulfield for pointing out a few gotchas at However:

fedup --network 20 --nogpgcheck

worked great.

  1. Axel says:

    [root@f19 ~]# fedup –network 20 -nogpgcheck
    usage: fedup SOURCE [options]
    fedup: error: unrecognized arguments: -nogpgcheck
    [root@f19 ~]#

  2. Axel, you need to write an additional hyphen before nogpgcheck. Correct syntax with long UNIX-style syntax usually takes 2 of them.

    #fedup -network 20 –nogpgcheck

    Hope it helps. =)
