How ro repair Ubuntu 10.04 LTS if the Update Manager and Synaptics don’t work

After I installed some new software I wasn’t able to update Ubuntu 10.04 LTS. The Update Manager was not able to check for updates and when I tried to use the Synaptic Package Manager I hadn’t better results. A reboot was not the right solution and I tested different ways to solve my problem saving the Ubuntu installation in my computer.

Searching on internet I discovered that there are few possible solution to avoid this problem and, in case you have the same bug on your computer, I decided to sum-up the most powerful after I successfully tried them.

First of all you can try to force the update process through the Terminal typing:

sudo apt-get update
sudo apt-get upgrade

If this doesn’t work you will try with this next step:

sudo rm var/lib/dpkg/lock
sudo dpkg --configure -a

Then launch again the Update Manager to verify if you succeed and if nothing happened solve the matter typing:

sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update

and try again to launch the Update Manager.

In my case this was enough to restore all the Update Manager features and solve the problem. If you have extra problems about this bug or if you want to suggest alternative solutions, please, don’t hesitate to comment this post.

How to manage the GRUB and purge old Kernel versions on the start-up menu

1 Reply

After a kernel update, you find the start-up menu populated with extra lines related to all the old kernel versions plus the current one. To manage the start-up manager and safely remove old kernels you have to manually operate on it.
First of all you have to double-check what is the current kernel version.
Open a Terminal and type:
uname -r
The result will be something similar to: 2.6.32-35-generic
Then you will go to the boot directory through the command:
cd /boot ls vmlinuz*
The next step will be to obtain more information about old kernel you have on our PC:
ls vmlinuz*
Now in the Terminal you have results similar to these:
vmlinuz-2.6.32-21-generic vmlinuz-2.6.32-25-generic vmlinuz-2.6.32-35-generic
vmlinuz-2.6.32-24-generic vmlinuz-2.6.32-26-generic
As last step you have to remove all the old version of the kernel using this command:
sudo apt-get remove linux-image-X.X.XX-XX-generic
where “x” is the obsolete kernel version you want to purge. In my specific case the proper command line I used was:
sudo apt-get remove linux-image-2.6.32-21-generic linux-image-2.6.32-24-generic linux-image-2.6.32-25-generic linux-image-2.6.32-26-generic
Last but not least go to System –> Administration –> StartUp Manager (available for installation on Synaptics or on Ubuntu Software Center) and select your OS choice in the Default Operating System menu. That’s all!

Sopcast represents one of the most popular technologies for live TV streaming, being based on the famous p2p system. However, until recently, there was no version of this software for Ubuntu and Linux in general. But now every single user can enjoy live TV right on their desktop or laptop computer with this absolutely amazing program.

In order to install Sopcast on your machine, here is what you need to do:

1. Open a new terminal. This is a classic step and is used in most of the installation processes you will encounter in Ubuntu.

2. In order to add Sopcast to Synaptic (the package administrator software integrated into Ubuntu) you will need to type the following command:
sudo add-apt-repository ppa:jason-scheunemann/ppa

3. The next step is related to the update of the sources list. This can be done with the following command, which needs to be typed into the same terminal in order to achieve the right effects:
sudo apt-get update

4. Now you will need to run Synaptic in order to finalize the process. This is usually done through the System menu (System -> Administration -> Synaptic). Alternatively, you can use the following simple command:
sudo synaptic

5. Look for the Sopcast package and install it. A very important step at this point is to not forget about all its dependencies. If you do not install everything, then Sopcast will not run correctly or not at all.

This is basically all you need to know if you want to install Sopcast on your machine. Whenever you need to run the player you can find it in the Application menu -> Multimedia -> Sopcast. You will surely enjoy the great variety of the channels available for every user through this system.
