Ubuntu system installs software with Deb package

Unlike Linux distributions like Redhat, Fedora and CentOS, the RPM package is used, http://www.aliyun.com/zixun/aggregation/33836.html "> Debian and Ubuntu use a Deb-formatted package. This section will cover several of the most important issues in mastering its usage.

How to manually install Deb

In general, there are two ways to manually install the Deb file. One is to use the files you have previously downloaded to your hard disk, and the second is to install them using Removable Storage like a CD.

Using downloaded files

Download the Deb file (usually a suffix name ". Deb") to a temporary path, such as/tmp. The second step is to install the package with the dpkg--install command. Here is an example of installing the NDISwrapper utilities package, which is typically installed with the Deb installation command:

root@u-bigboy:~# dpkg--install Ndiswrapper-utils_1.8-0ubuntu2_i386.deb selecting previously deselected package Ndiswrapper-utils. (Reading database ...) 70221 files and directories currently DWORD.) Unpacking ndiswrapper-utils (from Ndiswrapper-utils_1.8-0ubuntu2_i386.deb) ... Setting up Ndiswrapper-utils (1.8-0UBUNTU2) ... root@u-bigboy:~#

With CD

Installing the Deb file with a CD-ROM is similar to the situation in Fedora and Redhat. The difference is that the disc device name is/media/cdrom. The following steps will install the NDISwrapper Deb package that was previously copied to the disc:

1. Insert the disc, check the files under the/media/cdrom path, and then install Deb.

root@u-bigboy:/tmp# mount/media/cdrom-o unhidemount:block Device/dev/hdc is write-protected, mounting read-onlyroot@u-bigboy:/tmp# cd/media/cdromroot@u-bigboy:/media/cdrom# Lsndiswrapper-utils_1.8-ubuntu2_i386.deb root@u-bigboy:/media/cdrom# dpkg--install Ndiswrapper-utils_1.8-ubuntu2_i386.deb selecting previously Package Ndiswrapper-utils. (Reading database ...) 70221 files and directories currently DWORD.) Unpacking ndiswrapper-utils (from Ndiswrapper-utils_1.8-0ubuntu2_i386.deb) ... Setting up Ndiswrapper-utils (1.8-0UBUNTU2) ... root@u-bigboy:~#

2. After the end, eject the disc

root@u-bigboy:/media/cdrom# cd/tmproot@u-bigboy:/tmp# umount/media/cdromroot@u-bigboy:/tmp# Eject cdromroot@u-bigboy:/tmp#

Note: Unlike fedora, using multiple Cd/dvd,ubuntu is released with a CD/DVD disc. The Ubuntu installation process downloads any required packages from the Internet. Therefore, you may find that using apt tool is simple, it can automatically download and install most of the packages you want.
