preface
In ubuntu, there are three ways I know how to install an application: apt-get and dpkg install deb.
1. Installation through deb package:
Install.deb package:
Code:
sudo dpkg -i package_file.deb
Uninstall.deb package:
Code:
sudo dpkg -r package_name
2. Installation by apt-get:
The installation
Code:
sudo apt-get install package_name
The installation
Code:
sudo apt-get remove package_name
sudo dpkg -p package_name
Uninstall the package and its configuration files, but cannot resolve dependencies!
sudo aptitude purge pkgname
Uninstall software packages and their configuration files and dependency packages!
Clears all remaining configuration files for deleted packages
dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P
If the following error is reported, there are no remaining configuration files on your system, so don't worry

dpkg: --purge needs at least one package name argument
