(A)First search the package :
The traditional way:
dpkg -l | grep partial-name-of-package-to-be-removedUsing dpkg command ....more conspicuous way
dpkg -l '*partial-name-of-package-to-be-removed*'For example, you want to remove jdk then
dpkg -l '*jdk*'
(B)There are two ways to remove packages:
Using apt command : ...the better way...
After getting the list of packages choose the appropriate one and run following command
* To remove packages:
sudo apt-get remove package-name* To remove packages and dependencies:
sudo apt-get autoremove package-name* To remove packages, dependencies and configuration files:
sudo apt-get purge package-name
Using dpkg command : ...the crude way...
* To remove packages:
sudo dpkg -r package-name
* To remove packages,and configuration files:
sudo dpkg --purge package-name* To force removal, if got dependency error(this command turns errors into warning..):
sudo dpkg --purge --force-depends package-name
