3 things you need to remember when Upgrading to Fedora 23 as for the Unicmen’s instructions

The upgrade from Fedora 22 to Fedora 23 is not automatic, as usual in my Fedora experience, but it is really simple to manage if you follow the path suggested by Unixmen.

There are few things you need:

connect your laptop to the power plug (if you use a laptop);

– a couple of hours (something more or less depending on your CPU, RAM, Internet connection speed, etc..);

few lines of commands on the Terminal

The upgrading process is well structured and to start it you need to launch Terminal and upgrade the native Fedora Fedup with its new version that now is integrated into DNF:

dnf upgrade

Then you have to install the DNF plugin:

dnf install dnf-plugin-system-upgrade

and finally you can start the “core” part of the upgrade just typing:

dnf system-upgrade download –releasever=23 –allowerasing –best 

Where:

– allowerasing will continue the upgrade also in presence of any “old” (not yet upgraded) third part repositories that normally would have completely stopped the main upgrading process

-best is a verbose mode in case of unsatisfied dependencies

After a while, depending on your Internet connection speed, you will be able to conclude the upgrade typing:

dnf system-upgrade reboot

Your laptop will reboot and the upgrade starts.

From now you spend more than 40 minutes waiting and answering to few easy questions that the OS asks you to solve some configuration matters.

The length of the waiting time depends obviously on the CPU, the RAM and the type of Hard Disk installed into your PC.

That’s it!

If you liked YUMEX, don’t miss YUM EXTENDER (DNF) for Fedora 22

If you are one of them (like me) that prefer to manage and/or install software through an easy to use GUI, don’t forget to migrate to the new version of the “old” YUMEX.
Open your favourite Terminal and type:
su
dnf install yumex-dnf

Follow the instructions that appear on the screen and enjoy the new DNF GUI manager for Fedora 22.

Update from Fedora 18 to 20 or 21 in few simple clicks and without (I hope) problems!

Fedora 21Sometimes simple things become hard problems. This happened to me when I discovered that my Fedora 18 OS was obsolete (very old indeed) and I tried to upgrade it to the Fedora 20 version.

Fedora 18 doesn’t support the automatic OS upgrade so I had to spend some hours to find information on Internet and create the right DIY solution for my case. At the end of my little (sic!) research I discovered that I was able not only able to upgrade the PC to Fedora 20 but I also found a good “trick” to upgrade to the latest Fedora 21 following in just a couple of steps with the help of fedup and some other escamotages.

This is how I succeed…

First, you have to open a Terminal and type:

su
init 3

but you will immediately leave the Fedora GUI and so it’s better if you write the below commands on an -old style, paper notepad- to be sure to have all the right information in you hands and correctly manage the upgrade from Fedora 18 to Fedora 20

sudo su -
yum update
yum install fedup
fedup-cli --network 20 --nogpgcheck

It’s better to add –nogpgcheck because often you are not able to complete your upgrade for the “old”, “bad saved” gpg key in your system.

reboot

Now, at the boot-up menu (GRUB 2 menu) you have to choose “System Upgrade (Fedup)”.

Then just to be sure you really have an up to date OS, in Terminal, type:

Yum update

If you have problems with one or more of your “old” repositories don’t forget to deconfigure them. In my case I had to launch this command line in Terminal due to skip an old repository and proceed with the upgrade:

yum-config-manager --save --setopt=home_moritzmolch_gencfsm.skip_if_unavailable=true

At this point, to upgrade from Fedora 20 to Fedora 21 you have to open (again) the Terminal and type:

su
fedup --network 21 --product=workstation --nogpgcheck

OR

fedup --network 21 --product=server --nogpgcheck

(if your Fedora version is the server one)

OR

fedup --network 21 --product=cloud --nogpgcheck

(for the Fedora cloud edition for generic virtual machines or Container)

Take it easy and go to bed for a long snap because, in my case, the download took some hours as for 2,577 files to be upgraded…

At the end, as before, you have to Reboot and select “System Upgrade (Fedup)” at the boot-up menu (GRUB 2 menu) and all the necessary files will be installed. Again, take a good book to read while you wait the installation.

Good luck and remind you MUST backup all your data before you start any upgrade because unforeseen risks are always around the corner!

GrooveDown vs. GrooveOff: my personal experience using Grooveshark

Grooveshark is an online music service, very well-known and common especially in Europe. The quality of its mp3, offered just for listening is higher than what you find on YouTube and some programs were developed to allow listeners to search and listen songs without visiting the Grooveshark website.  Some of these software let you save sample of songs for a later listening but this habit doesn’t complain with the copyright laws in many countries so we discourage this kind of practice.

Today we would like to just endorse the ability of a single developer (www.caleta.fm) who was able to modify one of these programs, GrooveDown, and adapt it to the new website requisites.

This developer, using wireshark, was able to identify the misconfiguration between GrooveDown and the Grooveshark’s server and to positively update the data (client version and password) exchanged.

More in general I think that GrooveDown is the best client to listen to Grooveshark also because it is more powerful, fast and easy to use than its competitors. In particular, during some tests I did, I was positively impressed by the results I obtained using GrooveDown because I received better and more complete search results than using, for example, GrooveOff which is too a good software but, for my personal experience, gave back less impressive results.

Last but not least I want to underline that the caleta.fm development of GrooveDown is really stable and it was developed in two different versions just to be used with Java6 or Java7 platform. Recommended!

How to upgrade your Fedora system when the Software Upgrade doesn’t work!

Sometimes, if you use Fedora 18 – Spherical Cow, the Software Upgrade program couldn’t work properly. Software Upgrade shows you all the available upgrades but it is not able to install them. The download process starts but it will never finish and you wait for hours with no results. When and if you have this problem you can easily solve it launching a Terminal and typing the command:

yum update

In few minutes (depending on how many updates you need) your Fedora will be updated perfectly.

Last but not least, if you want to have a list of all the potential upgrades on your OS you can type:

yum list updates

and a complete list will be shown.  AddThis

Tux, the Linux penguin

Model B is interesting if you need a cheap PC that is able to run Linux (Debian GNU/Linux, Raspbian OS, Fedora, Arch Linux ARM, RISC OS, FreeBSD, Plan 9). When Model B will be upgraded to 1 GB RAM, we will have one of the most competitive computers for standard office tasks… ASFEE6HEF2PT

Using iPhone internet sharing over bluetooth under Linux

To use your iPhone’s internet connection through a Linux notebook over bluetooth, you have to open Tethering option on your iPhone device, under the Settings->General->Network section.

After that you can install Blueman (a simple and intuitive bluetooth manager) for easily configuring bluetooth PAN network:

apt-get install blueman

Start blueman-manager and find your mobile device and connect to it. When connection completed successfully, select Device->Add->Network Access Point in blueman-manager.
And the last step, configure the network interface:
