Here are easy ways to list upgrades available for installed packages on Fedora, Ubuntu and related Linux systems. Credit: Ian Noble; Modified by IDG Comm. Did you know that you can ask your Linux system to tell you what upgrades are available for the packages installed on it? You might be surprised by how many you’ll see, especially if you’re using the current release and don’t have your system set up for frequent or automatic updates. Updates play an important role in keeping your Linux systems secure and performing well. Since most packages are updated as fixes or improvements to the code become available, it’s hard to predict how many will show up on any particular day. (Note: Updates should be done when your system is not performing other important tasks.) Fedora and related systems To check what updates are currently available for your Fedora or related system, use a command like this: $ sudo dnf list upgrades Last metadata expiration check: 2:07:02 ago on Fri 23 Jul 2021 07:36:34 AM EDT. Available Upgrades audit.x86_64 3.0.3-1.fc34 updates audit-libs.x86_64 3.0.3-1.fc34 updates curl.x86_64 7.76.1-7.fc34 updates firefox.x86_64 90.0.1-1.fc34 updates libcurl.x86_64 7.76.1-7.fc34 updates libipa_hbac.x86_64 2.5.2-1.fc34 updates libsss_autofs.x86_64 2.5.2-1.fc34 updates libsss_certmap.x86_64 2.5.2-1.fc34 updates libsss_idmap.x86_64 2.5.2-1.fc34 updates libsss_nss_idmap.x86_64 2.5.2-1.fc34 updates libsss_sudo.x86_64 2.5.2-1.fc34 updates podman.x86_64 3:3.2.3-1.fc34 updates podman-plugins.x86_64 3:3.2.3-1.fc34 updates … On a system which hasn’t been upgraded in a week or so, you might easily see numbers like those shown below where we count all updates and then those that are security updates. $ sudo dnf list upgrades | wc -l 97 $ sudo dnf list upgrades —security | wc -l 35 Applying the upgrades To apply the available upgrades, you simply use a command like that shown below. The —refresh option marks the metadata as expired and forces the system to revalidate the cache. $ sudo dnf upgrade –refresh Fedora 34 - x86_64 36 kB/s | 12 kB 00:00 Fedora 34 openh264 (From Cisco) - x86_64 4.9 kB/s | 989 B 00:00 Fedora Modular 34 - x86_64 74 kB/s | 12 kB 00:00 Fedora 34 - x86_64 - Updates 41 kB/s | 10 kB 00:00 Fedora Modular 34 - x86_64 - Updates 61 kB/s | 11 kB 00:00 Dependencies resolved. ========================================================================================= Package Architecture Version Repository Size ========================================================================================= Upgrading: btrfs-progs x86_64 5.13-1.fc34 updates 971 k gnome-autoar x86_64 0.3.3-1.fc34 updates 55 k python-srpm-macros noarch 3.9-38.fc34 updates 20 k rust-srpm-macros noarch 18-1.fc34 updates 9.2 k Transaction Summary ========================================================================================= Upgrade 4 Packages Total download size: 1.0 M Is this ok [y/N]: y Downloading Packages: (1/4): python-srpm-macros-3.9-37.fc34_3.9-38.fc34.noarch.drpm 40 kB/s | 9.5 kB 00:00 (2/4): gnome-autoar-0.3.2-1.fc34_0.3.3-1.fc34.x86_64.drpm 47 kB/s | 13 kB 00:00 (3/4): rust-srpm-macros-18-1.fc34.noarch.rpm 114 kB/s | 9.2 kB 00:00 (4/4): btrfs-progs-5.13-1.fc34.x86_64.rpm 850 kB/s | 971 kB 00:01 [DRPM 1/2] python-srpm-macros-3.9-37.fc34_3.9-38.fc34.noarch.drpm: done [DRPM 2/2] gnome-autoar-0.3.2-1.fc34_0.3.3-1.fc34.x86_64.drpm: done ————————————————————————————————————————————- Total 667 kB/s | 1.0 MB 00:01 Delta RPMs reduced 1.0 MB of updates to 1.0 MB (5.0% saved) Running transaction check Transaction check succeeded.

Notice how the update process goes through a number of stages—upgrading, cleanup and verifying—and ends with a listing of the updated packages. At this point, no more upgrades are available. If you like, you can verify this by repeating the “list upgrades” command above. You should see a line like this with no updates listed. $ sudo dnf list upgrades Last metadata expiration check: 0:00:21 ago on Fri 16 Jul 2021 02:24:24 PM EDT. Ubuntu and related systems To see what updates are available on Ubuntu, Mint, and related systems, the command to use is apt list –upgradable. It will provide a list of updated packages. $ apt list —upgradable Listing...

Done Building dependency tree Reading state information... Done 16 packages can be upgraded. Run ‘apt list —upgradable’ to see them. The sudo apt upgrade -y command can then be used to apply all of the available updates to installed packages. Once that process is complete, you can repeat the apt list –upgradable command to show that there are no more available updates. $ apt list —upgradable Listing... Done Wrap-up Some Linux admins and users update their systems daily or weekly. Others set their systems up for automatic updates. In any case, it’s good to keep your system updated fairly regularly and to have some easy commands on hand to verify that your system is up-to-date.
