Where are all Ubuntu software installed?

Linux software installation is not the same as Windows software installation. Windows always installs a software in a specified folder, but Linux is different. Linux distributes the software to be installed in various folders of the entire system, for example, the configuration files of all software are installed under/etc, the library files required by the software are installed under/lib, and the log files are all under/var/log, /bin is a common program, and so on.

How can I check where all Ubuntu software is installed?

Complicated haha.
If you want to uninstall the deb package using Ubuntu apt, run the following command:
Apt-get autoremove XXXX can be uninstalled easily.

Where is the program installed in the ubuntu 1210 Software Center?

Programs downloaded from the software center are stored in/var/cache/apt/archives.

The location after installation is described below, which is complex.
If you only want to know where the files are after a software is installed, double-click the installation package and select "included files.

If you want to know where to start the software after installation, click Dash in the upper left corner and enter the software name or pinyin-you cannot enter Chinese characters. Or click the 2nd icon below and select "installed ".
After the software is started, the icon is displayed on the starter on the left. Right-click the icon and choose to lock it to the starter. Then it will remain there.
