Comprehensive Guide to apt-get

Last time I wrote up a comprehensive guide to yum for Fedora, openSuse, etc.. It was well received so I decided to focus on Debian based systems this time.

Debian is known to be extremely stable and reliable, and for its excellent package manager, apt. That’s why user-friendly Ubuntu decided to advantage of Debian package features, along with a number of other distributions. Just to show how easy it is to install something, try this:

sudo apt-get install vlc

All dependencies will be automatically fetched and installed along with the application. How easy is that?

A busy apt-get command at work. Woot.

Here is a list of some commands that might be useful to you.

Check your Ubuntu ISO for defects

ISO images are a great way to pack large amounts of data into one single file. This is useful for avid Linux users, distro hoppers, or just any tech enthusiast out there due to ease of use and portability. To learn more about ISO images, Wikipedia’s your friend.

With all these advantages, it is no wonder that ISOs are used quite often to distribute software. Coincidentally, that also includes our good ol’ popular Linux distributions such as OpenSuse, Fedora, Ubuntu, Debian, Mint, etc. (Please, I don’t need to hear about your fav distro).

Since these ISOs are large, have you ever wondered if there is a way to check to see if your downloaded ISOs are defective or not? I sure have. Fortunately, Ubuntu utilizes this thing called MD5 to ensure data integrity and authenticity and it is a breeze to check. Here’s how:

cd Desktop/ (assuming your ISO is located there).

md5sum ubuntu-8.10-desktop-i386.iso

Assuming the Ubuntu 8.10 Desktop ISO was checked, then it should return:

24ea1163ea6c9f5dae77de8c49ee7c03  ubuntu-8.10-desktop-i386.iso

MD5 result.
MD5 result. I passed!

My ISO passed. Yay! You know how I know? Here’s how.

Windows Users

MD5Sum is not supported in Windows, but there is a little free tool you can download here to do the same thing above.

Alright, I’m sure you are now curious to go and check your own downloaded ISOs. Go ahead, it’s perfectly okay.

Fedora 10 Preview Release is robust and pretty.

The Fedora Project finally released the last tester version of Fedora 10 before we get to see the real thing. If it is any good indication, which is usually the case, then we are going to have our hands on a very robust and solid release.

This new release still sports the simple and beautiful Nodoka theme. The new artwork theme is called Solar and it is amazingly pleasant and beautiful. Little things like this make all the difference. I have always been throughly impressed with how polished Fedora looks and feels, and it’s no different this time.

Fedora 10 also offers some nice features include:

  • Linux kernel version 2.6.27
  • The new Plymouth graphical boot system
  • Better webcam support
  • GIMP 2.6.2
  • GNOME 2.24
  • Better PulseAudio support
