Looking for more information about software packages such as maintainers, dependencies, sources, installation sizes, etc.?
There are several tools for communicating information about classic software packages
.deb Ubuntu Linux format. And I will show you one by one here.
1. apt show command:
All packages in the system apt repository (including valid PPA), if installed manually
apt show The command prints information about:
- Package version
- Installation size
- Package dependencies
- Apt-sources: The location where the package was installed, or the sources that provide the package.
- And a brief description of the software package.
apt show gnome-feeds The command prints something as the image shows.
deb If you manually install the binary, you will see the line “APT-Manual-Installed: Yes”.
2. Check package details via Synaptic Package Manager
Synaptic Package Manager has a Properties button. Search for and select a software package and the button will give you more details.
Is different from
apt show The command, Synaptic, displays both the libraries that the software package depends on and the system packages that depend on this package.
It also lists all the files that the package installs (or installs).
To install Synaptic Package Manager, run the command in your terminal.
sudo apt install synaptic
3. Gdebi package installer
If you just grab
deb If you create a package from the web, check all the files it contains, and all the dependencies are met, we recommend the Gdebi package installer.
You can also install the tool with the following command:
sudo apt install gdebi
4. Unzip Deb and check the details.
Even if you download it manually
deb For packages, you can open or unzip it from Archive Manager.
You will usually see data.tar.xz containing all the files you want to install, and control.tar.xz contains some scripts to run before and after installing or removing deb. And then there is a document file called “control” that contains some information about deb.
