Packages aremanuallyinstalled via the Something along the lines of: But of course the easiest ways to install a package would be,first,the GUI apps (Synaptic,Software Center,etc..),followed by the terminal commands Since dpkg is the base,you can use it to install packaged directly from the command line. Install a packagesudo dpkg -i DEB_PACKAGE For example if the package file is called Remove a packagesudo dpkg -r PACKAGE_NAME For example if the package is called Reconfigure an existing packagesudo dpkg-reconfigure PACKAGE_NAME This is useful when you need to reconfigure something related to said package. Some useful examples it the sudo dpkg-reconfigure keyboard-configuration Another great one is when you need to set the Timezone for a server or your local testing computer,so you use use the sudo dpkg-reconfigure tzdata |

If I run sudo apt-get install texlive-latex-base ,it has Failed for months with "Hash Sum mismatch". I can download the .deb file fromhttp://gb.archive.ubuntu.com/ubuntu/pool/main/t/texlive-base/texlive-latex-base-doc_2015.20150625-1ubuntu1_all.deb . If I install it using dpkg,would it subsequently be recognised (and updated) by apt-get.–

Debian (.deb) packages are the packages that are used in Ubuntu. You can install any .deb package in your system. .deb files can generally be installed from your file manager (Nautilus) merely by clicking on them,since file associations with the default installer is already set in Ubuntu. These instructions are for those who wish to install packages from the command-line terminal (Terminal).
To install a downloaded Debian (Ubuntu) package (.deb): Open Terminal and type
sudo dpkg -i packagename.deb
To remove a Debian (Ubuntu) package (.deb):
sudo dpkg -r packagename
To Reconfigure/Repair an installed Debian (Ubuntu) package (.deb):
sudo dpkg-reconfigure packagename
My favourite is GDebi,available from both terminal/shell or graphical desktop.
I usually associate.deb
files with GDebi as it is fast and efficient - especially compared to Ubuntu Software Center.One of the main feature of GDebi is it resolves dependencies and installs them.
For command-line runsudo gdebi <package.deb>
to install a single deb file.
