Updating a Fedora Standalone System (without internet connectvity)

Installing the latest updates of fedora on a standalone system which has not internet connection.
 I. Create a Fedora Update Repository:-

1) Take a System with Freshly installed Fedora OS connected to the internet for downloading the updates. The Fedora release versions should be the same as of the standalone system.

2) Create a folder to save to downloaded update.

            # mkdir /yumdownloader/

3) Execute the below command to download the latest packages with dependencies:

             # yum check-update | grep -v "anaconda\|Obsoleting" | awk '(NR >=2)' | cut -d " " -f 1 | tr "\n" " " | xargs -r yumdownloader --resolve --destdir /yumdownloader/

4) After completing the download, create an ISO image of the folder.

  

         # genisoimage -o fedora-updatesdeps.iso /yumdownloader

II. Installing updates on standalone system:-

         METHOD 1:-

      1. Mount the iso fedora-updatesdeps.iso on the standalone System which is required to be updated.

  

         # mkdir /mnt/iso/updates

       

       # mount -o loop /dev/sr0 /mnt/iso/updates

       # cd /mnt/iso

  

       # createrepo  .

       (install createrepo package if not present).

        # yum clean all

Then create a cdrepo.repo config file in /etc/yum.repos.d/

        # vi cdupdates.repo

 Add the below entries and save in the file:

        

         [cdupdates]

         name=CD REPOSITORY

     baseurl=file:///mnt/iso

     enabled=1

If required disable the other repos in the /etc/yum.repos.d/. In each file, change the setting enable=1 to enable=0

Once the above is done, execute the below command:

      # yum check-update

This should show the updates in the cdrepo. Then execute:

      # yum update

       Method 2:

    1.  The below method can also be followed:  

     # cd /mnt/iso/updates

        

         # rpm -Uvh *.rpm

NOTE:-

Method 1 shall keep a backup of the previous kernel version and can be seen in the GRUB menu, while Method 2 shall remove the previous kernel after upgrading.
