Ubuntu Software is the simplest way to install software, as it has a handy graphical user interface that displays screenshots, space requirements, and even user reviews. If you already have a . deb package that you downloaded from the web, you can install it using Ubuntu Software—just double-click the . deb file to open it in Ubuntu Software, where you’ll see an Install button.
If the app is already installed, you’ll see a Permissions button at the top, along with a red button that you can use if you’d like to uninstall it.
Open Ubuntu Software and click Installed at the top. Locate the application you want to uninstall. You can use the search box to filter the list or just scroll until you find it. Click the application and select Remove Enter your password to confirm. [2] X Research source
Apt is a great alternative to Ubuntu Software if you want to make sure you always have the latest versions of your favorite software. With Ubuntu Software, newer versions of the packages you install are not released nearly as often as they are on the various repositories available through Apt. You will need to use the sudo command to install packages with Apt. If you want to install software packages without root access, try the Snap Store.

If there’s a package you’re looking for that’s only available from a certain repository, you can add the repository using the add-apt-repository command. Check the instructions for the package you want to install for the repository name, public key, and other information.
For example, if you were looking for Firefox, you’d type apt-cache search firefox. All Firefox package names would appear in the search results. It’s not necessary to use sudo when searching the package index, as root permissions aren’t needed.
For example, running apt-cache showpkg firefox displays information about the package called firefox.
You can install multiple packages at a time by entering additional package names separated by spaces. For example, if you wanted to install both Firefox and the Chromium browser, you would enter sudo apt-get install firefox chromium-browser. If you already have the package installed and try to install it again, the package manager will check for a newer version and install it if it exists. After installing packages, you can use the sudo apt-get clean command to delete any package install files and free up some space on your hard drive.
First, run sudo apt-get update to update the package databases. If you just want to see which updates are available but not install them, use sudo apt-get list –upgradable. Then, run apt-get upgrade to check for and install updates for all software you’ve installed through apt-get. Or, if you just want to update one application, use sudo apt-get install <packagename instead.
If you also want to delete the package configuration files from the software you’re removing, use sudo apt-get remove
To install Synaptic, you’ll need to open a Terminal window and run sudo apt-get install synaptic.
If you need to add a repository or manage existing repositories, you can do so in Settings > Repositories. Synaptic shares its repository list with apt, so if you’ve added repositories to /etc/sources. list or used add-apt-repository in the past, that repository is already available in Synaptic.

First, update the repository list by pressing Ctrl + R or clicking Reload. Right-click a package and select Mark for Upgrade. Mark additional packages for upgrade if desired, then click Apply. Click Apply again to confirm.
Apps like Spotify, Slack, and Chromium can all be installed through the Snap Store. [7] X Research source If you have a file that ends with . snap already downloaded, you can install it without the Snap Store. Just run snap install . /filename. snap at the prompt, replacing filename. snap with the name of your file. If the file isn’t signed, you can add the –dangerous flag to the end of the command to skip the signature verification.
Software installed from Snap packages update automatically, so there’s no need to worry about updating your software.
However, if you want to manually update your software, you can run the command snap refresh at the prompt, or run snap refresh –time to find out when the next update is scheduled.
[8] X Research source You can also browse for and install Snaps from the command line, similar to using apt-get.
Run the snap command alone to learn how to use it.
[9] X Research source Run snap find
To see all installed snap packages, run snap list.
To delete a package, use snap remove
Open a Terminal window. Run sudo apt-get update to update the package database. Run sudo apt-get install build-essential to install the package.
First, use cd to enter the directory to which you saved the file.
If the file ends with .
tgz or .
tar.
gz, run the command tar -xvf
If you see a file with instructions, for example, one called README, you can read it using cat README (to display the whole file) or more README (to read it page-by-page). If both files are found, read them both!
If there isn’t a file called configure in this directory, re-read the instructions for installation steps. There may be additional instructions available where you downloaded the file, such as in a GitHub repository. Sometimes you’ll find a script called install. sh instead—if you see this, make it executable using chmod u+x install. sh and then run it using . /install-sh. If you get an error about missing dependencies or libraries, you’ll need to install whichever dependencies are required before you can compile the software. It’ll be easiest to do this using a package manager like #Advanced Package Tool (Apt) rather than downloading and compiling more source code. Once the required packages are installed, re-run the configure script until there are no errors.
