Installing software on Ubuntu is really easy but sometimes we can have problems to uninstall it if we have not used the Package Manager (Synaptic till Ubuntu 9.04 and later through the Software Center) or a .deb package. To fastly uninstall all the software you do not need or you are not fond of, you can type in the Terminal:
sudo dpkg -r your_file
An alternative and powerful way is typing:
sudo apt-get remove your_file
(where your_file it is the name of the software you want to remove)
or, if you want to completely cancel also the configuration files:
sudo apt-get --purge remove your_file
If you want to check what software is installed on you Ubuntu you can use:
and you will obtain a complete list of software and a very short summary for each package.
This week, in our Linux Page (in Spanish) we added a post about a new fantastic online service to manage and add software sources to your Sources List (System – Administration – Software Sources). Adding the right repository sources in Ubuntu is essential for a more practical and fast management of your OS. In fact, using the correct sources list you can be sure that your system is always updated and safe. RepoGen has been created for all these reasons. It also automatically compiles all the necessary GPG keys and you have just to add them (one by one) running the suggested command in the Terminal. We tested RepoGen on two different PCs running both Ubuntu 8.04 & Ubuntu 9.04 and were able to update our Software Sources in less of 15 minutes and without discovering a single problem. To conclude we strongly believe that RepoGen is an online service that can help you to save a lot of time and keep your Ubuntu always up-to-date! Strongly recommended!
Today, in our Linux Page (in Spanish) we added a brief news about Alien-GUI which is an interesting software developed to grafically (and automatically) convert tar, deb in RPM. As you already know, RPM is the package manager used to install software on different Linux system as (but not only) Mandriva, Fedora, Red Hat and Suse. Before installing Alien GUI, it is necessary to install Alien directly from Synaptics Package Manager (System – Administration). Alien GUi is very simple to use thanks to its intuitive graphic interface and it passed our test when we use it on a Mandriva. To sum up Alien Gui is a useful tool that sometimes could help all us to fastly solve some package compatibility problems in just few clicks. Recommended!
Today , in our Linux Page (in Spanish) we posted a brief review about installing Ubuntu Tweak and Moblock on Ubuntu 9.04. We have read different websites on these topics but the best are the official ones that we advise you to visit them: http://ubuntu-tweak.com/downloads for Ubuntu Tweak and http://moblock-deb.sourceforge.net/ for Moblock. Ubuntu Tweak is the most flexible graphical interface to configure desktop and system options on your Jaunty. On the other side,Moblock is a powerful software to protect your privacy when you surf internet and it is based on a huge list of IP address which are not considered as friendly.
We strongly believe that the most efficient solution is to add the sources on your Software Sources (System – Administration – Software Sources); for Ubuntu Tweak:
1 – using Terminal, import the key sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com FE85409EEAB40ECCB65740816AF0E1940624A220
2 – import the source on the Software Sources
