This post teaches you how to install, remove, Update, and search for software packages using the apt-get and apt-cache commands in Debian-based Linux distributions, such as Ubuntu, Debian<\/a>, and Mint.
\nIn this post, we provide proper instructions to help you manage packages in Debian and Ubuntu systems.<\/p>\n

What is apt-get?<\/span><\/h2>\n

Apt-get software is a compelling and free command-line program for package management. Moreover, people use this software to work with the APT Library in Ubuntu, which stands for Advanced Packaging Tool.
\nRuns new software packages, deletes existing software packages, updates existing software packages, or even upgrades the entire operating System.<\/p>\n

Users use the apt-cache Command to search the cache of the apt software package. Users use this tool to search for software packages, collect package information, and find existing packages ready to install for the Ubuntu or Debian operating System.<\/p>\n

5 Useful basic commands from apt-cache<\/span><\/h2>\n
\"5<\/h3>\n
How to list all available packages in Linux<\/h2>\n
How to find the package name and software description<\/span><\/h3>\n
To find the package name along with the description before installing it, we must use the search option. Using apt-cache, a search will display a list of matching packages along with a brief description. For example, to find the description of the vsftpd<\/strong> <\/a>package, run the following Command:<\/p>\n
PHP code:<\/p>\n
\n
$ apt-cache search vsftpd\r\n\r\nvsftpd - a lightweight, efficient FTP server written for Security\r\n\r\nccze - A robust, modular log coloriser\r\n\r\nftpd - File Transfer Protocol (FTP) server\r\n\r\nYasat - simple, stupid audit tool<\/pre>\n<\/div>\n
Moreover, run the following Command to find and list all packages starting with vsftpd:<\/strong><\/p>\n
PHP code:<\/p>\n
\n
$ apt-cache pkgnames vsftpd\r\n\r\nvsttpd<\/pre>\n<\/div>\n
How to check the package information<\/span><\/h3>\n
In the beginning, if we want to check the package information along with short descriptions (version number, summary, size, installation size, group, etc.), we must execute the following Command:
\nPHP code:<\/p>\n
\n
$ apt-cache show netcat\r\n\r\nPackage: netcat\r\nPriority: optional\r\nSection: universe\/net\r\nInstalled-Size: 30\r\nMaintainer: Ubuntu Developers <ubuntu-devel-discuss@lists.ubuntu.com>\r\nOriginal-Maintainer: Ruben Molina <rmolina@udea.edu.co>\r\nArchitecture: all\r\nVersion: 1.10-40\r\nDepends: netcat-traditional (>= 1.10-39)\r\nFilename: pool\/universe\/n\/netcat\/netcat_1.10-40_all.deb\r\nSize: 3340\r\nMD5sum: 37c303f02b260481fa4fc9fb8b2c1004\r\nSHA1: 0371a3950d6967480985aa014fbb6fb898bcea3a\r\nSHA256: eeecb4c93f03f455d2c3f57b0a1e83b54dbeced0918ae563784e86a37bcc16c9\r\nDescription-en: TCP\/IP Swiss Army Knife -- transitional package\r\nThis is a \"dummy\" package that depends on Lenny's default version of\r\n\u00a0netcat, to ease upgrades.

How to check the dependencies of a particular package<\/span><\/h3>\n
The showpkg option for the apt-cache Command checks the prerequisite packages for the desired software. Also, whether these prerequisite packages are installed on the System or not. To do this, run the following Command:<\/p>\n
PHP code:<\/p>\n
\n
$ apt-cache showpkg vsftpd\r\n\r\nPackage: vsftpd\r\nVersions:\r\n2.3.5-3ubuntu1 (\/var\/lib\/apt\/lists\/in.archive.ubuntu.com_ubuntu_dists_quantal_main_binary-i386_Packages)\r\n\u00a0Description Language:\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0File: \/var\/lib\/apt\/lists\/in.archive.ubuntu.com_ubuntu_dists_quantal_main_binary-i386_Packages\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0MD5: 81386f72ac91a5ea48f8db0b023f3f9b\r\n\u00a0Description Language: en\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0File: \/var\/lib\/apt\/lists\/in.archive.ubuntu.com_ubuntu_dists_quantal_main_i18n_Translation-en\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0MD5: 81386f72ac91a5ea48f8db0b023f3f9b\r\n\r\nReverse Depends:\r\n\u00a0\u00a0ubumirror,vsftpd\r\n\u00a0\u00a0harden-servers,vsftpd\r\nDependencies:\r\n2.3.5-3ubuntu1\u00a0\u00a0- debconf (18 0.5) debconf-2.0 (0 (null)) upstart-job (0 (null)) libc6\u00a0\u00a0(2 2.15) libcap2 (2 2.10) libpam0g (2 0.99.7.1) libssl1.0.0 (2 1.0.0)\u00a0\u00a0libwrap0 (2 7.6-4~) adduser (0 (null)) libpam-modules (0 (null)) netbase\u00a0\u00a0(0 (null)) logrotate (0 (null)) ftp-server (0 (null)) ftp-server (0\u00a0\u00a0(null))\r\nProvides:\r\n2.3.5-3ubuntu1 - ftp-server\r\nReverse Provides:<\/pre>\n<\/div>\n
